- Moreover, silicone rubber gasket sheets are known for their durability and long service life. Their inherent elasticity allows them to withstand compression set, meaning they can maintain their original shape even after prolonged use. This property is particularly beneficial in applications where constant pressure is applied, such as pipe connections and machinery seals.

b) The area where the oil seal is seated is to be plunge ground in order to prevent wear grooves that normally tend to wear out the lip of the oil seal at a faster rate.
Remove the cylinder head (See How to remove a cylinder head ), carefully peeling off the old gasket from the head or block. Make sure no dirt or carbon falls into the engine.

Nitrile is suitable for environments that have a temperature range of -30 degrees Fahrenheit to 250 degrees Fahrenheit. It is compatible with a variety of fluids, such as hot & cold water, silicone oil, animal & vegetable fat, hydraulic fluid, and gas oil. Nitrile is also a perfect material to use for any application that needs shock absorbers as it’s resistant to grease and abrasion.
In fact, modern and outstanding engine concepts require new and outstanding properties and solutions for dynamic seals, which continuously can withstand the high loads.
Oil seals are used to keep chemicals apart from lubricants such as oil/fat or water away to keep spinning shafts or bearings in proper working condition. Rotary shaft Seals are among the most commonly used seals for sealing lubricating oil, water or grease in different applications.
