Cork-rubber gaskets use evenly sized cork particles distributed evenly throughout the rubber binder . Result is a compressible valve cover gasket without leak paths. Our gasket gaskets are .170 in thicker than standard valve cover gaskets. These gaskets create a positive seal by controlled swelling of the gasket material when exposed to hot engine oil. Provides excellent flange sealing and durability.
