The Honda 18381-ZE1-801 Muffler Gasket is a genuine OEM component designed for a wide range of Honda engines and power equipment, including GX110, GX120, GX140, GX160, and GX200 horizontal shaft engines, EB2200 and EB2500 generators, HS521, HS522, HS55, HS621, and HS622 snow blowers, F401 and F501 tillers, and WA20, WA30, WB20, WB30, WD20, WD30, WH15, WH20, WT20, and WT30 water pumps — among others. As a direct Honda OEM part, this Muffler Gasket is manufactured to the same specification as the original, ensuring a proper seal between the exhaust system and the muffler. Confirm part number 18381-ZE1-801 against your machine's serial number before ordering, as Honda periodically supersedes parts at production breaks.
Key Features
- Genuine OEM Exhaust Sealing — manufactured by Honda to provide the correct clamping and sealing performance between the muffler and the exhaust port, preventing combustion gases from escaping at the joint.
- Broad Cross-Equipment Coverage — fits GX-series horizontal shaft engines, Honda generators including the EB2200 and EG2200, HS-series single- and two-stage snow blowers, F-series tillers, and a full range of Honda water pumps. Confirm fitment to your specific unit using the compatibility table.
- Direct OEM Replacement — matches the original gasket's dimensions and material grade exactly, so this part drops into place without modification during a standard muffler service.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks across many of the machines this gasket covers; check your unit's serial number against the fitment table to confirm part number 18381-ZE1-801 is correct for your build.
The Muffler Gasket forms the sealing interface between the engine's exhaust port and the muffler body. Its job is to contain hot exhaust gases and prevent them from leaking at the joint — a leak here causes audible exhaust noise, a loss of back-pressure that can affect engine performance, and exposure of nearby components to exhaust heat. When this gasket deteriorates, burns through, or is disturbed during muffler removal, it must be replaced to restore a proper seal. Installing a correctly specified OEM gasket ensures the muffler seats squarely and the exhaust system functions as intended.
