The Honda 16957-Z2E-003 Petcock Gasket is a genuine OEM Petcock Gasket designed for GX440 horizontal shaft engines. As a direct Honda OEM component, this gasket is manufactured to the exact specification required for a proper fuel shutoff seal on the GX440. Confirm your engine's serial number against the fitment table before ordering to ensure this is the correct version for your unit.
Key Features
- Fuel-Tight Seal — as a genuine OEM gasket, this part is made to the exact profile and thickness Honda specifies for the petcock port, eliminating the gaps that allow raw fuel to seep past a worn or degraded original
- Direct OEM Replacement — designed as a drop-in replacement for the original gasket on GX440 engines, with no fitting adjustments needed
- Serial Number Awareness — Honda supersedes parts at production breaks, so verify your GX440 serial number against the fitment table to confirm part number 16957-Z2E-003 is correct for your engine
The petcock gasket forms the sealing interface between the fuel shutoff valve and the fuel tank or valve body on the GX440 engine. It prevents fuel from leaking past the petcock connection point when the valve is in use or closed. When this gasket deteriorates, shrinks, or cracks, the result is a fuel leak at the shutoff valve — a condition that wastes fuel, creates a fire risk, and can make the engine difficult to keep running reliably.
