The Multiquip 12251ZE3W00 is a genuine OEM Cylinder Head Gasket GX340 designed for GA6HZ, MVH304GSB, GAW180HE, GAW180HE1, and GAW180HEA series equipment. As a direct Multiquip OEM part, 12251ZE3W00 is manufactured to the exact material and dimensional tolerances required by the GX340 engine, ensuring a proper combustion seal from the first startup. This part is a direct fitment for operators running GA6HZ generators, MVH304GSB reversible plate compactors, and GAW180HE series gasoline arc welders who need a fast, confident repair.
Key Features
- OEM Combustion Sealing Integrity — Manufactured to the exact material grade and crush specification required by the Honda GX340 engine, delivering a consistent, leak-free seal between the cylinder head and engine block.
- Direct Drop-In Installation — Matches the original bolt pattern, port openings, and gasket profile of the GX340 engine so it seats correctly without trimming or reworking mating surfaces.
- Broad Equipment Compatibility — Confirmed fitment across GA6HZ gasoline generators, MVH304GSB reversible plate compactors, and GAW180HE, GAW180HE1, and GAW180HEA gasoline arc welders.
- Maintains Engine Compression — A correctly seated cylinder head gasket preserves combustion pressure and prevents coolant or oil from migrating into the combustion chamber, keeping power output consistent across the operating cycle.
- Fuel and Combustion Safety — A failed or improperly seated head gasket can allow combustion gases to escape toward fuel system components. Using the correct OEM replacement eliminates that risk on GX340-powered equipment.
The cylinder head gasket forms the critical pressure seal between the engine block and the cylinder head on the Honda GX340 engine. It contains combustion gases within the cylinder during the power stroke while also preventing engine oil and any coolant from entering the combustion chamber. When a head gasket fails — whether from overheating, improper torque, or normal wear — the result is lost compression, oil consumption, or white exhaust smoke, all of which degrade machine performance and can lead to more serious engine damage if left unaddressed. Replacing it with the correct OEM part restores the integrity of the combustion chamber and protects the engine's long-term health.
