With their synthetic-rubber construction, not only can Fel-Pro Performance Fel-CoPrene valve cover gaskets offer good sealing characteristics, but they can also offer significantly longer life than conventional cork gaskets. Note, however, that because of their higher flexibility, they require the use of a quick-drying contact cement to bond them to the valve cover before installation.
