The Honda 18381-ZE7-800 Muffler Gasket is a genuine OEM replacement designed for GXV160 vertical shaft engines, HR216 lawn mowers, and HRA216 lawn mowers. As a direct OEM component, this gasket is manufactured to Honda's exact specifications, ensuring a proper seal between the muffler and the engine's exhaust port. Honda supersedes parts at serial number breaks, so confirm your unit's serial number against the fitment table before ordering to make sure part number 18381-ZE7-800 is the correct match for your machine.
Key Features
- Exhaust Sealing Integrity — engineered to the precise thickness and port geometry Honda specifies for the GXV160, HR216, and HRA216, delivering a gas-tight seal at the muffler joint
- Genuine OEM Component — sourced directly from Honda, this gasket meets the same specification as the original, so there is no guesswork about fitment or sealing performance
- Serial Number Awareness — Honda revises part numbers at production breaks; check your engine or mower serial number against the compatibility table to confirm this is the right gasket for your unit
- Exhaust Leak Prevention — a failed or deteriorated muffler gasket allows hot exhaust gases to escape at the joint, leading to audible exhaust noise, carbon buildup around the port, and potential heat damage to surrounding components
The muffler gasket forms a heat-resistant seal between the exhaust port on the engine and the inlet flange of the muffler, preventing combustion gases from escaping at that joint. When the gasket is intact, exhaust is routed cleanly through the muffler, which reduces noise and directs gases safely away from the operator and machine. Over time, heat cycling causes the gasket material to harden and compress unevenly, leading to leaks that show up as a louder exhaust note, soot deposits around the muffler flange, or a noticeable drop in muffler effectiveness — replacing a worn gasket restores the proper seal and brings exhaust performance back to spec.
