Cometic AFM intake gaskets are constructed from a chemically blown, compounded nitrile synthetic rubber bonded to an aluminum core. The gasket material has a temperature resistance of over 250 degrees and an 85 percent recovery, while maintaining strong torque retention. Cometic AFM intake gaskets are ideal for machined surfaces, especially uneven stamped surfaces that have been plated. AFM intake gaskets retain torque and require no additional sealers.
