The gaskets are mostly made of rubber. Due to the long service life of the vehicle, the rubber material will age and harden, resulting in oil leakage. Oil dripping onto the road causes environmental pollution and inconvenient cleaning. Therefore, the car needs to be checked regularly in case something goes wrong.

Common materials and characteristics of Oil seal

Common materials for oil seals are: nitrile rubber, fluororubber, silicone rubber, acrylic rubber, polyurethane, PTFE, etc. Nitrile rubber: it has good heat resistance, wear resistance, resistance to various lubricating oils, greases, oil-gas mixtures and other applicable temperatures -30~120 degrees Celsius, but can not be used in phosphate ester hydraulic oil and gear oil containing extreme pressure additives, stable performance in gasoline and low aniline point mineral oil.

Advantages of oil seal
