The Honda 18333-ZB7-800 Exhaust Pipe Gasket is a genuine OEM component designed for EP2500, EU6500, and EU7000 generators, EX3300, EX4500, and EXW171 generators, the EXW171 welder generator, and GX390 horizontal shaft engines. As an authentic Honda part, it is manufactured to the same specification as the original, ensuring a proper seal at the exhaust pipe joint. Confirm your unit's serial number against the fitment table before ordering, as Honda updates parts at specific serial breaks.
Key Features
- Genuine OEM Sealing — sourced directly from Honda, this gasket delivers the compression and heat resistance an exhaust pipe joint demands, not a generic approximation of it.
- Direct-Fit Replacement — engineered to match the original profile, this part drops into place without modification, restoring a flush, leak-free joint at the exhaust pipe connection.
- Broad Fitment — covers EP2500, EU6500, and EU7000 inverter generators, EX3300, EX4500, and EXW171 generators, and GX390 engines; verify your serial number against the fitment table to confirm the correct application.
- Exhaust Integrity — a failed or deteriorated exhaust pipe gasket allows hot exhaust gases to escape at the joint, causing noise, odor, and potential heat damage to surrounding components.
The exhaust pipe gasket sits at the junction between the exhaust pipe and the engine's exhaust port, forming a gas-tight seal that contains combustion byproducts and directs them safely out through the exhaust system. When this gasket deteriorates or burns through, exhaust gases leak at the joint, producing a distinct ticking or hissing sound under load and allowing hot gases to escape where they are not intended. Replacing a worn gasket with a genuine Honda part, such as part number 18333-ZB7-800, restores the sealed exhaust path and protects the surrounding engine and equipment components from unintended heat exposure.
