Description
Overview:
This exhaust gasket is a Genuine Part for Honda GX-series small petrol engines, designed to seal the joint between the cylinder head exhaust outlet and the exhaust manifold/muffler. It prevents hot gas leaks, helps maintain correct back pressure, and supports smooth engine running. Made from heat-resistant gasket material suitable for exhaust temperatures, it compresses on installation to create a reliable seal. The flat, two-bolt-hole profile aligns with the exhaust flange for a straightforward fit. Ideal for common site and garden machinery powered by GX140 and GX160 engines, such as generators, water pumps, pressure washers, plate compactors, and tillers. It serves as a direct replacement for worn or damaged gaskets during exhaust or muffler maintenance, helping protect the cylinder head and exhaust components from erosion and carbon blow-by.
