Do-it-yourself plastic window lubrication: types and methods of lubricating plastic window fittings


PVC profile care

There are various tips: how and what is the best way to wash plastic windows and PVC profiles in particular. However, the most traditional remedy, soapy water, is generally suitable for removing household dust and street dirt.
The smooth surface of the plastic profile does not have microcracks and relief (unlike wooden windows), therefore, a soft cloth, rag or sponge (housewives make their work 50% easier thanks to the use of rags containing microfiber) moistened with soapy water perfectly washes away everything mud.

How to deal with stubborn dirt or, for example, foam on the PVC profile?

To clean the plastic profile from dirt left by a marker or other dyes, we recommend using a melamine sponge dipped in water and squeezed out. The sponge copes well with surface dirt.

To clean the profile from the remains of the polyurethane foam, you can use a special composition for cleaning the polyurethane foam, or, after waiting for the foam to dry, remove the dry foam with a hard, non-scratch object, for example, a wooden spatula.

If there are traces left on the profile that could not be removed with a melamine sponge, then you can use a professional stubborn stain remover (for example, COSMOFEN). The disadvantages of this cleaning agent should be pointed out that its effect destroys the surface layer of PVC and in this place the profile in the future, without protection, will "attract" dirt more intensively than untreated areas.

How to wash plastic windows

Do not use scouring pads or cleaning agents containing abrasive grit (such as Pemolux), acid, alkali, solvent or acetone. Their use destroys the surface structure of the PVC profile.

Why lubricate windows

Ordinary housewives know that rubbing parts of assemblies and parts must be lubricated regularly. For example, they, if necessary, process sewing machines or door hinges with machine oil without the participation of a strong half of humanity. For some reason, no one is in a hurry to grease the windows, although their situation is worse than at the doors.

Even a short-term opening of the sash leads to the deposition of street dust on all metal parts, including grease. Every year the amount of dirt in the oil is growing, making it difficult for the locking devices and fittings - the abrasive effect of impurities is manifested. If you do not take measures, accelerated wear of rubbing units and striking plates, which can not always be found on sale, may occur.

Attention: the loss of the oil layer leads to excessive friction in the mating parts, which manifests itself in the appearance of extraneous sounds: clicks, grinding or squeaking (often all together) - their appearance requires immediate treatment of all rubbing parts with lubricating oil.

Manufacturers of mechanisms and accessories do not produce interchangeable parts, which leads to an expensive replacement of the entire locking system in the absence of a tiny detail from another company. Lubrication of plastic windows solves several problems at once:

  • increases the wear resistance of rubbing parts;
  • makes the operation of the locking mechanism noiseless;
  • facilitates the process of opening (closing) the leaves;
  • protects metal from rust;
  • allows the seal to maintain its elasticity, preventing it from stretching or cracking.

If prevention is ignored or done incorrectly, several unpleasant surprises await window owners:

  • unpleasant extraneous sounds appear when opening / closing the doors;
  • due to the friction of metal on metal, metal dust appears between the rubbing surfaces, which accelerates the wear of parts;
  • rubber under a layer of dust quickly loses its elasticity, which leads to the penetration of cold air into the apartment in winter;
  • replacement of worn-out parts is not always possible - manufacturers of locking mechanisms and accessories often change the model range of their kits, and it is very difficult to find a replacement for a part that was produced 5-6 years ago.

Cleaning of drainage channels

Special channels are milled in the profile to remove accumulated moisture. You can see them outside the frame - on the outside, street, side of the window and inside the frame.

Dust and dirt particles enter the holes together with moisture. If you do not remove dirt from the drainage holes of the plastic profile in time, this can lead to damage to the window and its failure.

We strongly recommend that you inspect the windows for dirt in the drainage channel and remove any blockages.

Care of seals

When washing the window, clean and lubricate the sealing rubber located around the frame and sash. If you do not monitor the condition of the tapes, then in 2-3 years they will lose their elasticity and become fragile.

Lubricating the seal will help extend the life of the seal.

After you have removed dirt and dust from the seal, apply a little silicone grease on it (you can use glycerin-based products), spread over the surface with a clean cloth and rub.

It is sufficient to lubricate the seals twice a year. Such care of the seal will keep the elasticity of the rubber. You will be rewarded with more reliable protection from precipitation and drafts.

The better to lubricate plastic windows

During preventive maintenance, the question arises: how to lubricate the mechanism of plastic windows, fittings and seals. Let's figure it out.

Mechanism

Almost all known lubricants are suitable for lubricating locking mechanisms:

  • Silicone-based lubricants - produced specifically for locking devices for plastic, wooden and aluminum windows. Can be purchased in tubes or spray cans;
  • Universal silicone lubricants - used for any mechanisms;


Lubricant for plastic windows.

  • Machine oil for sewing machines - easy to apply and long-lasting on lubricated parts;
  • All types of rubber and plastic neutral (printed on the package) mineral, semi-synthetic and synthetic lubricating oils (excludes spindle and diesel engine oil - too fluid).

Important: some experts consider WD-40 grease ideal for a window mechanism - it creates a protective waterproof film on its surface. The second part is categorically against its use - at low temperatures it does not work well as a lubricant, it thickens. The editorial staff of the StroyGuru portal did not find any compelling arguments either for its use or against it. Therefore, it is better to refrain from such a purchase and purchase special products, where 3 types of lubricant are presented: for rubbing parts, accessories and seals.

You should not try to find a replacement for the oils listed above. The use of some household or improvised means is strictly prohibited:

  • vegetable and animal oils (sunflower, rapeseed, butter, etc.);
  • petroleum jelly;
  • shoe cleaning products (gel, wax, spray);
  • oils for 2-stroke internal combustion engines;
  • margarine.

The listed funds thicken in the cold, which complicates the operation of all window systems, and also collects dust well.

Sealing rubber bands

It is a little more difficult to understand the issue than to lubricate the sealing gum on plastic windows. Profile sites recommend several professional and home remedies. The following are classified as professional:

  • "Fenoflex" is a German product specially created for window seals (according to the creators, it increases their resource by 20-25%);
  • Lubricant for sealing gum from kits for window care, etc. Come on sale in cans or bottles made of plastic with special nozzles for squeezing out the lubricant;
  • Technical silicone is the most affordable care product for any rubber product, and the best at the same time. It is easy to apply, odorless, transparent. Retains properties at temperatures ranging from -50 to + 230oС.

The WD40 solvent is also classified as a professional product, with which we strongly disagree. Any solvent must be fluid. The fluidity is provided either by kerosene or alcohol (there may be its derivatives) - there is no way to say for sure, since the manufacturer has classified the composition of the product.

Everyone knows about the results of the interaction of both of these substances with natural rubber or artificial rubber - over time, the molecules of the material lose the ability to move relative to each other (elasticity is lost), the product becomes fragile and cracks or stretches.

Practice confirms: a one-time exposure to WD40 seals will not harm them. Long-term leads to the fact that the seals literally jump out of the grooves.

Among the home remedies, it should be noted:

  • Glycerin is a colorless viscous liquid, a product of fat saponification. It performs well its functions indoors. However, problems begin outside: it dissolves in water (in the rain), which requires frequent lubrication of the seals from the outside;
  • Vaseline - excellently softens rubber. It does not dissolve in water, which protects the seal from rain. The problems lie in the area of ​​temperature regime: it can withstand frost only up to -25oС, and in case of heat (over + 27oС) it begins to melt. Therefore, with significant temperature changes, reapplication of the protective layer is required.

Lubrication instructions are simple:

  1. the elastic bands are wiped with soapy water with a soft cloth or sponge, after which they are wiped dry with a napkin;
  2. if the seal has two petals, first the surface between them is lubricated, and then the outer one;
  3. liquid products (glycerin) are applied with a cotton swab or sprayed if sold in cans;
  4. viscous substances are applied by hand (silicone, petroleum jelly) or with a brush;
  5. proper care of rubber bands provides for 2-time lubrication: in spring and autumn.

How to lubricate the fittings of plastic windows

The answer is simple and laconic: by the same means as locking mechanisms.

Instructions for lubricating plastic windows. Manufacturers of window fittings and sash opening / closing mechanisms sometimes indicate the place of lubrication. For the rest of the owners, we give a diagram (see photo below), which shows at what points the lubrication point.


Lubrication points for windows.

Lubrication of the window begins with washing the glass unit and profiles (frame and sashes) with special means and then cleaning all elements of the sash and frame from dirt, dust and old grease. To do this, the sash opens alternately in different planes, so that you can first clean and then lubricate the locking devices for different opening modes.

All metal parts are wiped with a sponge, brush or damp cloth, after which they are wiped dry with a dry cloth or cloth. In this case, you must follow two simple rules:

  • no detergents for metal parts;
  • the weather should be calm - dust, soot, volatile fats, etc. can get onto the cleaned surface with the wind.

Lubrication is applied according to a simple algorithm:

  • after washing and cleaning, the window is ventilated (dried);
  • all moving parts, mounting brackets, bolts and latches are lubricated (methods of applying lubricant are shown in the photo);


The tubular spout helps you get to the most difficult points.


Lubrication of windows with aerosol.

  • after lubrication, the window is closed and opened several times in each plane - thus, the lubricant is spread over the entire surface of the lubricated parts.

A few tips:

  • It is most convenient to lubricate with a syringe.


Lubrication of windows with a syringe.

  • Spray cans contaminate the plastic and seals next to the part to which the spray was applied (even with a spout tube) - you will have to wipe it again. Therefore, it is best to avoid them.
  • From plastic bottles, it is enough to squeeze 1-3 drops to the lubrication point.


Lubrication of parts using a plastic bottle.

  • All parts of one window must be lubricated at the same time.

If all procedures are performed correctly, the window will extend its service life by several years. But it is not worth the risk and prophylaxis should be repeated regularly.

How and how to wash a double-glazed window

Double-glazed windows of a plastic window with the appearance of dirt and even more scratches on them, significantly reduce the light transmittance. Because of this, more energy is consumed to illuminate the room than it could otherwise. Therefore, it is extremely important to keep the glass clean by regularly washing away dirt. To clean glass, warm water with a small amount of liquid detergent for glass and dishes is quite suitable.

Tinted glasses and glasses with a special coating can be washed in exactly the same way, since the decorative surface is hidden inside a sealed bag. You should not be afraid for her.

The exception is special decorative coatings with a reflective effect (not to be confused with a heat-reflecting glass coating, an energy-saving glass unit). The choice of detergents for cleaning such glasses should be approached with extreme caution. We recommend, first, to check how the agent acts on the coating in a small area, and, only after that, apply the agent to clean the entire window.

What can not be washed double-glazed windows

Do not use powder or abrasive cleaners. Under no circumstances should any glass contamination be removed with sharp objects.

To spend less time on washing window glass - pay attention to new types of self-cleaning glass units. More details about these products will be consulted by the managers of the Business-M Window Company.

How to care for a plastic window sill

The window sill is one of the most noticeable elements of the PVC profile, so you need to take care of it very carefully.

Removing scratches

It would seem, where do scratches on a plastic window sill come from if they did not appear during installation? The author of the article also thought that there was nowhere, until her child began to test the strength of this element of the window with an iron hammer for beating meat. Naturally, after such (albeit quickly terminated) "procedure" it was impossible to look at the poor windowsill without tears. And this was still lucky, because at the age of one and a half, the son did not realize that it was more interesting to break glass than plastic! So, I would never have believed it, but you can hide deep scratches without a trace.

If the mechanical damage is shallow, the area where there are scratches is wiped with a solvent, which "eats" the top layer of plastic, leveling it. After that, wash the agent with a damp cloth and grind the window sill. This is done using a straight grinder, having previously wrapped its cylinder with sandpaper and fur for grinding.

If the recesses on the windowsill are quite large, you can seal them with liquid plastic after using the solvent.True, it is always worth remembering that after using it, the color of the treated areas will differ from the main shade of the window sill. An alternative to using such products is a primer. After priming the window sill, it is completely painted.

A special putty will also help to save from scratches. You can buy it in the form of a powder, which you dilute in the desired consistency at home. Before sealing chips and recesses, the window sill is cleaned of all contaminants, dried, degreased. After that, you can apply the composition to the scratches. The putty dries on average in 15 minutes.

The most reliable way to get rid of scratches is to use special pads, which is almost comparable to replacing a window sill, but is a simpler procedure. To implement this method, you just need to choose an overlay with your favorite pattern or a plain one and stick it on the windowsill using mounting glue. After that, this window element will be reliably protected from ultraviolet radiation, it will remain just as easy to clean, but at the same time it will also look original.

Washing rules

To wash rough window sills, you can use coarse dishwashing sponges (most importantly, not metal scrapers), for a smooth or laminated surface, soft sponges or microfiber napkins are optimal. You can use an old toothbrush with almost worn soft bristles to clean the space between the frame and the window sill, where the sponge will not climb.

If the window sill is not very dirty, a soapy solution is suitable for washing it, which was used to clean the entire PVC profile. To clean rusty and other stubborn stains from windowsill, it is best to purchase special cleaners suitable for plastic surfaces. So, the universal Mr. Proper, Cillit Bang spray, Pemolux, etc.

They must be used strictly in accordance with the instructions. It is important to rinse off the products well, since traces of the detergent will literally attract new dirt.

Getting rid of yellowness

Under the influence of ultraviolet radiation and even chlorinated water, plastic can acquire an unpleasant yellowish tint. It is believed that the listed store-bought window sill cleaning products also help to get rid of yellowness on the PVC profile. However, it is advisable to acquire them only for the simultaneous disposal of stubborn dirt. But folk remedies will help to return the original whiteness to the windowsill.

Soda ash and laundry detergent

To whiten a window sill:

  • mixed in a liter of warm water for 1 table. a spoonful of soda and powder, carefully dissolve so that there are no grains,
  • the solution is impregnated with the fabric and carried out along the windowsill,
  • the windows are left like this for 10-15 minutes,
  • the solution is washed off with clean water.

Alcohol

Any kind of alcohol is applied to the fabric and the windowsill is wiped with it. This should be done with gloves and in a well-ventilated area. After the procedure, the plastic is wiped with a cloth soaked in clean water.

Special means

If the situation is completely critical, and the windows have turned yellow completely, except, of course, the double-glazed unit, you can try products designed to clean the PVC profile. These include Defender 30504 and COSMOFEN 10. In fact, these are weak solvents that can only be used on matte plastic. Before using them, they must be applied for a couple of minutes on an inconspicuous area of ​​the window to see the "reaction" of the plastic.

Before applying the product, the window sill is washed and wiped with a dry cloth, then treated with the selected chemical. If the yellowness has not disappeared from the first time, the procedure is repeated. After clarification, the window sill is wiped with a damp cloth.

Care of fittings

The correct functioning of the window primarily depends on the quality of the window fittings, first of all, its movable elements: hinges, locks, latches.

In order to ensure the stable operation of the window, it is necessary to avoid the ingress of foreign objects between the frame and the sash, as well as into moving parts. Do not hang clothes or other foreign objects on the sashes.

Lubricate the fittings with oil (for example, machine oil) and this will significantly increase the service life of the entire window.

Operation of double-glazed windows

How to properly wash plastic windows is not known to everyone, therefore, often cleaning double-glazed windows turns into a long and ineffective procedure. Most of the problems are caused by newly appearing smudges, which force the glass to be wiped several times after the window has been washed. This happens when the profiles from the street side remain dirty, and cloudy drops drip from them onto the glass. To prevent this from happening, you must first wash and wipe the frames, and only then start the double-glazed windows. The best way to wash plastic windows in such cases depends on the degree of contamination of the outside. In most cases, warm water is enough, which is recommended to be changed several times to clean water.
Street dust and organic matter from glass can be removed well with ordinary heated water. For stubborn dirt, it is recommended to use a warm soapy water solution first. Double-glazed windows are washed up and down and after the procedure is completed, you need to remove moisture with a soft microfiber. In order not to leave streaks, clean glasses are wiped dry with paper towels. Household chemicals are needed only to add shine or remove stubborn dirt. After all, after applying it, stains are almost always left, which have to be removed with clean paper towels. If you do not find out in advance how to clean the windows correctly, this process will be not only long and ineffective, but also make you spend money on unnecessary household chemicals. However, as we can see, with the right approach, expensive funds are not required.

Double-glazed windows must not only be kept clean, but also adhere to certain rules during operation. If the recommendations are not followed, the thermal performance of the windows deteriorates. Depressurization of double-glazed windows is also possible. To avoid the problems mentioned, you must follow the precautions:

  • do not install double-glazed windows at a distance of less than 300 mm from heating devices and 200 mm from the floor level;
  • avoid sudden changes in temperature;
  • do not change the orientation of glass units independently recommended by the manufacturer;
  • do not stick films on unhardened glass that can change its optical properties;
  • do not allow the humidity level in the interior to rise above 60%.

Only if all the recommendations are followed will windows be able to maintain their original energy efficiency and sound absorption level longer.

Adjusting plastic windows with your own hands

If you notice that the window sash does not close, it touches the frame when opening / closing - you need to adjust the sash, returning it to the correct position.

There are several ways to eliminate sagging of the sash and the most effective solution is selected depending on the identified cause. When you are not sure of your strengths and knowledge, do not know how to close a plastic window - contact our master for help. Having correctly diagnosed the cause, the master will be able to guarantee that after the repair, the problem will not recur. Simple problems of PVC windows can be solved by a dispatcher by phone.

When you urgently need to repair a window and set up a plastic window or balcony door so that it closes or opens, adjusting the fittings will help.

If your window is equipped with adjustable fittings (for example, Roto NT) - you can eliminate the sash sagging yourself by adjusting the hinges.To do this, it is enough to have a set of hex keys: 4 mm or 6 mm - depending on the type of fittings.

Sealing rubber processing

The sealing rubber is located around the perimeter of the sash and frame. It ensures the tightness of the structure. Under the influence of sunlight and moisture, rubber breaks down and loses its elasticity. The most dangerous periods for her are late autumn and early spring. During the day it absorbs water, at night the moisture freezes and expands, which leads to rupture and cracking. The use of special water-repellent lubricants that form a protective film on the surface can extend the life of the rubber by several seasons more than without treatment. Therefore, it is advisable to take care of the rubber seal annually.

DIY maintenance instructions for sealing rubber:

  1. Wash off dust from the seal with soapy water and dry.
  2. Apply a thin layer of silicone grease from the special kit to the entire surface of the elastic using a soft cloth.
  3. Leave for a few minutes (the time is indicated on the package, on average 10-20 minutes).
  4. Wipe off excess product with a dry soft cloth.

Important! The composition of the lubricant should not contain alkalis, alcohol, solvents.

If the rubber is already worn out: it has become dry and hard, cracks and tears have appeared on it, only its replacement will help. You can order this service from a company servicing windows, but it is much cheaper to do it yourself, you just need to purchase a seal of a suitable type. They have a different shape and number of cameras, in order not to make a mistake with the choice, you need to pry on the old rubber band at the junction of its ends, cut off a small piece or take a picture of the cut. To calculate the required footage of the seal, measure the sash perimeter and multiply by 2.


Sealing contours on the sash.

How to install the rubber correctly:

  1. Remove the old rubber seal from the groove inside the frame.
  2. Rinse thoroughly and dry the groove.
  3. Cut off the rubber with a margin, so that it is completely enough for the entire perimeter of the sash. The fewer joints, the better the tightness. The use of short lengths is not allowed.
  4. Insert one end of the rubber into the groove. It is better to start from the middle of the opening. You cannot make a connection in the corner.
  5. Place the elastic into the groove around the perimeter without stretching. Especially carefully you need to work out the corners. The cord should not be tightly gathered into an accordion.
  6. The junction can be glued.
  7. Replace the rubber seal on the sash in the same way.

Advice! You should not glue the sealing rubber around the entire perimeter - it will be problematic to replace it later. If the seal is selected correctly, it will hold tightly in the groove and without glue.

Window adjustment winter-summer

Window sashes with adjustable fittings can be switched to winter and summer mode - adjust more or less tight fit of the sash to the frame.

This type of adjustment may be necessary if the existing mode does not suit you: over time, there is a feeling of blowing, or, conversely, the fittings close too tightly. Although the modes are called "summer" and "winter", it is not at all necessary to adjust the trunnions every time the season changes.

Adjusting windows for the winter

assumes a tighter junction of the sash to the frame, to exclude a draft.

Window adjustment from winter to summer mode

weakens the clamping of the sash to the frame, reduces the load on the fittings and, as a result, reduces the wear of the fittings themselves. Use a summer clamp when high tightness is not required - this way you will significantly extend the service life of the fittings.

Setting the clamp from summer to winter and vice versa is the only type of action for adjusting a plastic window, which is not difficult to do on your own, since it is extremely simple and straightforward. You can make it yourself, having only a hexagon.

How to adjust a plastic window in winter mode and vice versa

First, you need to determine the places where you want to strengthen the vestibule. Find the closest locking element (locking pin).

Pay attention to the marker on the pin - a dot or a serif. This is a pressure indicator. To ensure a more dense bridging "for the winter", you need to turn the trunnion with a hexagon to such a position that the marker points to the side of the room (away from the street), to loosen and transfer to summer mode, turn the trunnion to the position "with the marker in the direction of the street".

How to adjust a plastic balcony door

You can set up a balcony door for summer and winter pressure in the same way as a plastic window, since exactly the same hardware mechanisms are used for its manufacture.

What kind of lubricant to choose

The first step is to figure out what composition is best for lubricating. Any technical oil intended for mechanisms is suitable.

You can lubricate metal parts with ordinary machine oil, which is used to lubricate the elements of a sewing machine, if there is one in the house.

A silicone based lubricant can be used. But such formulations are also sold that are specifically designed for this procedure. They are sold either in plastic bottles or in metal cans. The supplied attachments are very convenient for lubrication.

Home craftsmen most of all give preference to the lubricant composition "WD-40". All movable mechanisms that form the system are processed:

  • fasteners;
  • constipation.

Selection criteria for window lubricants

You need to take care of window structures with high-quality and proven means. Poor lubricant quality will result in reduced machine life. When buying, be guided by the region of residence, because some products have the property of "tanning" at low temperatures.

How to lubricate plastic windows
Aerosol for lubricating plastic windows

Check with the seller in the store which lubricant is suitable for your plastic window model. Choose products in aerosols. This is the most convenient and economical lubricant. By spraying, you can reach the most inaccessible parts of the mechanism. It is not necessary to buy expensive products. Often they contain components found in inexpensive lubricants, and the principle of operation is the same.

What cannot be used

There are products that are strictly forbidden to use to lubricate windows.

Lubrication of plastic window fittings prohibited lubricants

  1. Vegetable oil. When it dries up, it creates a dense layer that mixes with dust and turns into dirt that is difficult to remove.
  2. Products that contain acids and alkalis. They quickly destroy the protective coating and reduce the performance of the entire structure.
  3. Kerosene based products.
  4. Most types of automotive oils and products that are used to lubricate the gun.

The use of these materials is strictly prohibited. They produce not only a negative impact, but also provoke premature breakdowns.

If the elements need urgent lubrication, it is better to pay attention to quality substances. This will reflect on successful functionality in the future.

How to lubricate the mechanism of plastic windows

The following products will be the best choice for lubricating window mechanisms:

  • silicone based products specially made for window mechanisms. When applied to a metal surface, a thin, resistant film is formed. The lubricant is available in tubes or sprays. Both options will work;
  • universal grease, which contains the same silicone. It is identical to the special tool, but it can be used not only on windows. The consumption of funds is minimal, so one tube will last for a long time;
  • lubricating oil for sewing machines or bicycles.Similar to machine oil, but better cleaning. It is easy to use and stays on the surface for a long time;
  • mineral or synthetic lubricants. The main thing is to choose products that do not include acids, aggressive reagents and abrasives.

It is not recommended to use any vegetable fats, petroleum jelly, shoe polish for lubrication. This is due to the fact that vegetable oils leave a film on the mechanisms that dries for a very long time, about two weeks. During this time, a large amount of dust accumulates on it, which complicates the operation of the fittings, accelerating its wear.

Types of products for plastic windows

What can not be used to lubricate the fittings of plastic windows? Products containing acids and chemicals destroy the metal surface, “eat up” the anti-corrosion layer and oxidize the parts. Guns and automotive oils are also not suitable. The former are expensive, and do not perform protective functions in relation to windows. The latter have a low degree of purification.

How to lubricate rubber bands on plastic windows

The seals also need care. You can buy special lubricants, or you can use the tools at hand:

  • silicone based lubricants;
  • silicone sponges;
  • pharmacy glycerin, but only in pure form, without cosmetic additives.

Do not use petroleum jelly and baby powder. Also, do not choose products containing a solvent, alcohol and alkali. They will destroy the structure of the rubber.

There is a controversial opinion about the use of WD-40. Some argue that the use of an aerosol will create a protective waterproofing film on the surface. Others say that at low temperatures, the agent can thicken and interfere with the operation of window mechanisms. If only this tool is at hand, it can be used to lubricate the seals.
