Importance of Quality Oil Seals in Automotive Applications:
The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
Oil gasket seals are used in various parts of the engine, including the valve cover, cylinder head, and oil filter housing. These seals are designed to prevent oil leaks and maintain the integrity of the engine components. The oil gasket seal ensures that the engine remains properly lubricated and free from oil leaks, contributing to its overall efficiency and reliability.
Despite being incredibly flexible, silicone has some significant drawbacks. The toughness, resistance to wear, and abrasion of many silicone compounds are poor. If you seriously need an oil seal material with better strength and resistance to high temperature, the perfect option is Viton.
