Seals are essential to protecting the bearings of any rotating shaft assembly -They prevent contaminants such as dirt, dust and water, while also preserving the system’s lubricant.

Valve cover gaskets and head gaskets play pivotal roles in maintaining the proper functioning of the engine. The valve cover gasket prevents oil leaks and contaminants from compromising the lubrication and performance of the engine, while the head gasket ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and preventing the mixing of oil and coolant. Both gaskets are critical for the overall efficiency, performance, and reliability of the engine.

Many oil seals are capable of resisting contact with grease, fuel, water, and other elements. Knowing what type of fluid the seal will interact with will help you choose the right oil seal that can withstand those types of fluids.
