There are several key factors to consider when selecting the right oil seal to best protect your application.
Rubber Valve Cover Gasket: Essential Sealing Component in Vehicle Engines
A wide range of industries rely on oil seals to ensure optimal operation of mechanical assemblies. Components in the industrial and automotive fields, such as pumps, fans, electric motors, and other rotating or moving parts, use oil seals to maintain lubrication and keep contaminants from entering the shaft. Seals are especially useful in applications exposed to extreme environmental temperatures and pressures.

Why Is Bearing A Seal Important?
Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.
