Hydrogenated nitrile rubber (HNBR)
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.



Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
Types of oil seals

The most common and economical material within the sealing industry, Nitrile, is used in many oil applications, the automotive sector for aircraft fuel applications, military and marine applications, and more.
Does it mean the seal stops the leakage completely? Well, on the practical grounds yes because there is no ‘visible leakage’.
Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.
