Valve cover gaskets are made of a variety of materials, including synthetic rubber, cork rubber or molded rubber. Cork rubber is the most common material used on older engines, and molded rubber is most popular on today’s engines. The latest innovation in valve cover gaskets is the rigid carrier with a molded-silicone sealing bead.

Federal-Mogul's Fel-Pro® brand offers two lines of premium valve cover gaskets: PermaDry® and PermaDryPlus®.

PermaDry gaskets, made of molded rubber, are excellent as replacement parts on engines that were originally equipped with molded-rubber gaskets. PermaDryPlus gaskets have a rigid carrier and molded-silicone rubber sealing bead. They are designed and built specifically to seal difficult problem leaks.
