Mr. Gasket Performance Valve Cover Gaskets are high-density cork/rubber blend gaskets that use evenly sized cork particles distributed evenly throughout the rubber binder. The result is a compressible valve cover gasket without leak paths. 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. For original equipment replacement, high performance street, drag race and oval track use.

Features:

  • Manufactured from high-density cork/rubber blend gasket material
  • Provides excellent sealing and durability
  • For OE replacement, high performance street, drag race and oval track use

Using his own '57 Chevy as a rolling testbed, drag racer Joe Hrudka launched the most famous gasket company in the world more than half a century ago. Mr. Gasket is the go-to gasket source for racers with gaskets and fasteners that seal perfectly every time.
