Description
Overview:
This exhaust gasket is a non-genuine replacement for Honda part number 18381-ZH8-800. It sits between the exhaust outlet on the cylinder head and the muffler or exhaust manifold to create a gas-tight seal. Made from a heat-resistant, compressible composite suitable for exhaust temperatures and vibration, it helps prevent leaks, soot blow-by, and loss of performance. Designed for small petrol engines, it is suitable for Honda GX110 and GX120, and also fits GX140 and GX160 units commonly found in compactors, generators, pressure washers, pumps, and mixers. A sound seal reduces noise, protects the mating faces from erosion, and supports stable idling and power. This is a practical replacement during routine servicing or when refitting the exhaust after repairs.
