The Honda 12251-ZE6-000 Cylinder Head Gasket is a genuine OEM replacement designed for GXV120 vertical shaft engines, HP400 power carriers, and HR194, HR214, and HRA214 lawn mowers. As a direct Honda OEM component, this gasket is manufactured to the exact specifications required for a proper head seal on each covered application. Always confirm your machine's serial number against the fitment table before ordering. If your machine is among the models listed, this is the correct OEM head gasket to source.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the correct material grade and sealing profile for the GXV120 engine and each compatible machine in this fitment list.
- Combustion Seal Integrity — the cylinder head gasket seals the joint between the cylinder head and the engine block, maintaining compression and preventing combustion gases from escaping. A failed or worn gasket leads to compression loss, overheating, and oil contamination.
- Broad Compatibility — fits GXV120 vertical shaft engines as well as HP400 power carriers and HR194, HR214, and HRA214 lawn mowers; check your serial number against the fitment table to confirm your specific unit is covered.
- Serial Number Verification Recommended — Honda updates gasket specifications at production breaks, so matching your machine's serial number to the fitment table is an important step before installation.
The cylinder head gasket sits between the engine's cylinder head and the cylinder block, forming a critical pressure seal around the combustion chamber. It must withstand the repeated thermal cycling and combustion pressures generated during normal engine operation — if it fails, compression drops, exhaust gases can leak into the cooling passages, and oil or coolant contamination can follow. Replacing a compromised cylinder head gasket with a correct OEM part restores full compression and protects the engine from the internal damage that a degraded seal allows.
