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.
Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
