Cometic Honda CB750 2 Valve 71-78 Valve Cover Gasket

Valve Cover Gaskets are constructed from AFM or thick fiber materials that are best suited for each specific application.

• AFM is a chemically blown, compounded nitrile synthetic rubber bonded to an aluminum core with temperature resistance of over 250F. AFM material has an 85% recovery while maintaining strong torque retention. AFM does not require gasket sealers or re-tightening.
• Aramid Fiber is a premium hi-temperature, hi-density creep resistant material that requires no re-torquing and is fuel resistant. All Cometic fiber materials are asbestos free and require no additional sealants.
