Permatex® Optimum Black Gasket Maker, 80mL Carded Tube

Permatex OPTIMUM BLACK Gasket Maker combines maximum oil resistance with high flexibility. Many modern engines now involve gasket joints with dissimilar materials including plastic-to-steel and aluminum-to-steel. As the engine heats up, these components have different rates of expansion and contraction. Combine this with lighter weight and thinner materials, the demand on a gasket to perform at optimum levels has never been greater. The strength and flexibility of OPTIMUM BLACK meets and exceeds the specification to reliably seal lightweight and high-performance assemblies. It is sensor safe, low odor and non-corrosive with resistance to oil, shop fluids and thermal cycling. OPTIMUM BLACK is one of the most advanced, high flex, maximum oil resistant RTV silicone gaskets available.
