Fabricated from performance CRC
(core-reinforced-composite), Edelbrock Valve Cover Gaskets provide
excellent sealing integrity and conformability for easy
installation. The multi-layer construction has two highly
compressible, high rubber content, fiber-reinforced outside layers
which are chemically bonded to a high strength composite core. This
unique core-reinforced construction has a radial strength to resist
high-vacuum or blow-out conditions.
