SCE engineers have combined the elements of carbon and copper to form a completely new and durable exhaust gasket. CopperClad Exhaust Gaskets feature a reinforced graphite gasket body with unique copper armor at each port, similar to the fire rings of a head gasket. This combination of materials provides superior heat resistance, compressibility and strength for a tight, permanent seal in extreme conditions. Recommended for high heat applications such as; Racing, Towing and Performance.
