Polymer Valve Covers
Our Polymer Valve Covers are constructed of a high performance polymer which is heat, impact and chemical resistant. Each cover weighs 2 3/4 pounds and is 3/16” taller on the inside to provide ample clearance for all valve train components. Leak free sealing is obtained by using a flat and square gasket rail with grippers to hold the gasket in place. High bolt bosses ease removal and add strength to prevent cracking and breaking at the mounting holes. The valve cover breathers are easily modified by hole-sawing a 1 3/16”hole to mount breather stands or vac-u-pan in desired location. Our polymer valve covers are available in red, black, blue and yellow.
