Description
Overview:
This Genuine Honda gasket (18381-Z1V-000) is an exhaust/muffler sealing gasket for Honda vertical-shaft engines, including GXV160H2 and GXV160UH2. Built from a heat‐resistant composite, it sits between the cylinder exhaust port and the muffler flange to create a gas‐tight seal. By preventing exhaust leaks, it helps maintain engine efficiency, stable back pressure, correct noise levels, and cleaner operation. Designed to the original Honda specification, it offers an exact fit with the correct bolt pattern and port alignment. Suitable for professional and domestic garden machinery that uses these Honda engines, such as pedestrian rotary mowers and commercial walk‐behind units used by landscapers, groundskeepers, and councils.
