Valve cover gaskets and head gaskets are essential components in automotive engines, serving distinct yet crucial roles in maintaining the integrity and functionality of the engine. The valve cover gasket seals the junction between the valve cover and the cylinder head, preventing oil leaks and contaminants from entering the engine. On the other hand, the head gasket seals the cylinder head to the engine block, ensuring the containment of combustion gases and the separation of oil and coolant passages.

J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.

Lip seals are passive mechanical devices used to close the shaft exit points on electric motors and other rotating machinery. The seals are made to keep moisture and dust out of the machinery’s inner constructions while having little to no impact on how well they work.
