Description
Overview:
This Exhaust Gasket (3-bolt pattern) is a Genuine Honda part for GX-series industrial engines, including the GX240 and GX390. It sits between the cylinder head/exhaust port and the muffler or exhaust manifold to create a reliable gas-tight seal. Made from a heat-resistant composite suitable for high-temperature, high-vibration environments, it helps prevent exhaust leaks that can reduce engine efficiency, increase noise, and cause hot gas blow-by. The three-bolt triangular form ensures even clamping and a stable seal on the Honda exhaust flange. Ideal for routine servicing or when refitting the silencer, this gasket is engineered for a precise fit on Honda GX240, GX270, GX340, and GX390 engines commonly found in compactors, generators, pressure washers, pumps, mixers, and other plant and garden equipment.
