Cometic's AFM differential cover gasket for Dana 35 (.060" thickness) is a purpose-built sealing solution using a chemically blown nitrile synthetic rubber bonded to an aluminum core. The AFM material recovers strongly (about 85%) while retaining torque, tolerates temperatures above 205°F, and is asbestos-free. It does not require sealants or re-torquing, making it a practical choice for differential cover applications.
