Replaces OEM part # For:
Sierra part # 18-0102 Exhaust manifold gaskets
These gaskets are constructed from proven, hi-temperature composites, capable of reaching over 500 degrees Fahrenheit. The gaskets do not include harmful asbestos materials, which give off harmful fumes when heated. Gaskets are capable of withstanding higher heat and exhaust pressures, which are commonly found in the marine environment.
Each exhaust manifold gasket ensures factory matched footprint of exhaust ports, allowing exhaust to flow freely through the manifold, avoiding damage from blocked ports. The typical thickness of each gasket is 1/16".
The exhaust manifold gasket comes as a complete set with precise CAD cut gasket to eliminate hand cutting or trimming for proper alignment. It is recommended during installation to clean both surfaces to the bare metal and apply a thin layer of high-temperature silicone sealer on the surface side to ensure the ultimate seal.
