As most O-rings and seals are made of synthetic elastomeric polymers, i.e., “rubber” material such as nitrile, EPDM, and Neoprene, they are the best lubricants for them derived from synthetic compounds. At the top of the list is silicone-based and ester-based lubricants.
MicroLubrol ATD lubricant is a 100% pure PFPE oil excellent for reducing squeaks, rattles, and wind noise in convertibles and other automotive parts. Recommended for retractable convertible roof top rubber seals and sliding convertible roof top rubber seals.
WD-40® High Performance Silicone Lubricant is ideal for use on rubber materials. After you have allowed time for the glue to dry and settle, spray the entire rubber surface with WD-40® High Performance Silicone Lubricant, and wipe away with a clean microfiber cloth.
Apply a grease-based lubricant, such as petroleum jelly, by dipping a paper towel into the container, then rubbing the lubricant onto the door gasket. Coat the entire gasket thoroughly, wiping excess off one area and onto another.
WD-40 Specialist® Silicone Lubricant safely lubricates, resists water and protects metal and non-metal surfaces such as rubber, plastic and vinyl. This formula dries fast and leaves a clear, non-staining film that doesn't stick or make a mess, so it won't attract dirt.
Silicone spray lubricant is safer to use on rubber and plastic. A silicone spray like WD-40 is excellent for rubber seals as it is safer for use on rubber and plastic, so it continues to seal correctly.
WD-40 Specialist High Performance Silicone is your go-to silicone based lubricant spray that works well on all tools, rubber pipes, window seals, linkages, valves, locks, doors, plumbing fittings and belts.
WD-40 Specialist silicone lubricant helps keep rubber components safe. The lubricant can withstand temperature from -35°C to +200°C. The lubricant protects rubber parts from attracting dust and prevents moisture. Give the rubber seals at least an hour to settle properly and then apply the lubricant.
As said, vaseline will degrade the rubber seals. Even Halfords sell silicone spray for this very purpose.
Silicone oils are dielectric and so is silicone grease, silicone is generally low cost and widely available. However we do not recommend using any silicone based lubricant for use on electrical connectors or contacts.
Look to any manual or set of directions, and it is highly recommended to lubricate most seals before installing or changing them properly. Proper lubricants help protect O-rings from damage due to abrasion, pinching, or cutting, all of which could lead to premature product failure.
Synthetic oil: Synthetic oils, such as polyalphaolefin (PAO) or ester-based oils, can also be used to lubricate rubber suspension bushings. These oils are known for their excellent lubrication properties and resistance to high temperatures and heavy loads.
Vegetable oil isn't just for use in the kitchen. Some engine manufacturers recommend vegetable oil to lubricate O-Ring seals. In these applications, if petroleum-based lubricants are used, the result will be swelling and cracking of the seal, leading to a leak.
Silicone and PFPE are generally safe with all plastics. Synthetic hydrocarbons and mineral oils are usually compatible with most plastics, though high and low operating temperatures may rule out mineral oils.
WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint.
Return rain boots' luster. If your rubber wellies get chalky after a few wears, rub them with olive oil to erase the white marks. Avoid getting oil on the soles, though; it may cause you to slip next time you put them on.
So is vinegar safe to use in your dishwasher or washing machine? Here is what I found: It is safe for natural rubber seals and any parts made from polypropelene, silicone, fluorocarbon, and virgin Teflon, as well as butyl synthetic rubber seals.
Silicone is hard to get off and can build up on your skin, leading to acne. It can especially cause irritations for people who have sensitive skin and cause your skin to become even more sensitive. If you are acne-prone and oily, using silicone-based products will make it even worse.
A: WD-40 is a petroleum based product which means it will degrade plastic or rubber over time… Silicone will not.
Although it is best to purchase and use water-based or silicone-based lubricants, there are alternatives people can consider if they are unable to do this. These include aloe vera, yogurt, olive oil, and virgin coconut oil.
White lithium grease most often has a petroleum base. Due to its formulation, it's unadvisable to use it near or on rubber or plastic. This can cause premature degradation of the material.
Silicone-based lube is very slippery and long lasting and is safe to use with condoms. However, silicone-based lubes cannot be used with silicone sex toys, as they can damage the toy. Silicone-based lubes may be more difficult to wash off skin than water-based and may stain sheets, so keep that in mind.
By far the most suitable lubrication solution for rubber is a carefully formulated emulsion of oil and water emulsion. This is because it can overpower rubber's low surface energy. Effectively, this means that emulsion-style lubricant can completely coat the surface of rubber without any beading.
