COMETIC’s Primary Cover Gasket utilizes a proprietary AFM (Aluminum Foamette Material) construction, featuring an aluminum core bonded to a chemically‑blown, compounded nitrile synthetic rubber exterior. This dual‑material design delivers resistance to temperatures exceeding 205 °F while maintaining an 85 % shape‑recovering capability and strong torque retention, making it well suited for machined primary surfaces.
The kit is complete, providing all gaskets, seals, and O‑rings required for both the inner and outer primary. Manufactured in the USA, the gasket set does not require the application of a gasket sealer.
