Description
Cometic exhaust gaskets are designed with application-specific materials and construction to provide lasting, leak-free performance. For 4-stroke engines, these gaskets feature a double-sided Viton® rubber-coated stainless steel construction. This design ensures a precise, high-temperature seal capable of withstanding extreme conditions. The exhaust gasket kits are engineered for extreme temperatures, employing a steel-tanged outer layer that grips the Armor-400 inner layer. This Armor-400 inner layer is heat-resistant up to 1,800ºF, providing ultimate resistance against blow-outs or push-outs caused by over-torquing. These gaskets provide maximum sealing and longevity, making them ideal for demanding applications.
