The Honda 18381-ZE6-820 Muffler Gasket is a genuine OEM Muffler Gasket designed for GXV120, GXV140, and GXV160 vertical shaft engines, the HP400 power carrier, and a wide range of Honda lawn mowers including the HR194, HR195, HR214, HR215, HR216, HRA214, HRA215, HRA216, HRB215, HRC215, HRC216, HRM195, and HRM215. As a genuine Honda part, it is built to the exact specifications required for a proper, leak-free seal at the muffler joint. Confirm your machine's serial number against the fitment table to ensure this is the correct gasket for your unit before ordering.
Key Features
- Genuine OEM Sealing Performance — manufactured to Honda's exact tolerances, ensuring the muffler gasket seats flush and holds a consistent seal at the exhaust port under heat and vibration cycling.
- Direct-Fit Replacement — this gasket is matched to Honda part number 18381-ZE6-820 and installs directly without modification, restoring the original exhaust connection.
- Broad Fitment Coverage — compatible with GXV120, GXV140, and GXV160 vertical shaft engines, the HP400 power carrier, and more than a dozen Honda lawn mower models including the HR, HRA, HRB, HRC, and HRM series.
- Serial Number Verification Recommended — Honda supersedes gaskets at production breaks, so check the serial number on your engine or mower against the fitment table to confirm this is the right part for your specific unit.
The muffler gasket forms the sealing interface between the exhaust port on the engine's cylinder head and the muffler itself. It prevents hot exhaust gases from escaping at the joint, keeping combustion byproducts routed safely through the muffler and away from the operator. When this gasket fails or burns through, exhaust leaks at the port — producing a loud popping or ticking noise, reducing back-pressure, and exposing nearby engine components to excessive heat. Replacing a worn muffler gasket with a genuine Honda part restores the exhaust seal and returns the engine to normal, quiet operation.
