Description
Overview:
This Genuine Honda gasket (OEM No. 18381 Z1C 801) is a heat‐resistant exhaust/muffler gasket designed to create a secure seal on Honda GX‐series petrol engines. Manufactured from durable stamped metal suitable for high temperatures, it prevents exhaust leaks at the muffler joint, helping maintain correct back pressure, quieter operation, and consistent engine performance. It is engineered for a precise fit on engines including the GX340UT1 and GX390RT1 used across construction and garden machinery. Typical applications include generators, pressure washers, water pumps, plate compactors, tillers, and other equipment powered by Honda GX240, GX270, GX340 and GX390 variants, where a reliable exhaust seal is essential for efficiency, emissions control, and component longevity.
Key Features:
- Genuine Honda part for assured compatibility and performance
- Heat‐resistant metal construction for reliability at exhaust temperatures
- Precise fit to reduce exhaust leaks and maintain engine efficiency
- Helps protect surrounding components from hot gas blow‐by
- Supports stable idle and power output by preserving correct back pressure

- Suitable for heavy‐duty site use and frequent start/stop cycles
Typical Applications:
Used at the exhaust/muffler joint on Honda GX240-GX390 family engines powering generators, pumps, plate compactors, concrete saws, pressure washers, chippers, and snow throwers.
