Commonly used in oil pump, clutch cover, ignition cover, etc. AFM is the ideal gasket material for machined surfaces, especially two uneven stamped surfaces that have been plated. AFM is a chemically blown, compounded nitrile synthetic rubber bonded to an aluminum core. It has a temperature resistance of over 250°F. AFM has an 85% recovery while maintaining a strong torque retention. No gaskets sealants or silicon bead is required. Re-torque is also not required.
