The Multiquip 12251ZF1800 is a genuine OEM Cylinder Head Gasket designed for a wide range of Multiquip and Whiteman equipment powered by compatible Honda engines, including the MVC90H plate compactor, WM70S/P mortar mixer, QP205SH centrifugal pump, MC64P/S concrete mixer, and MP-series masonry saws. As a genuine OEM component, it is manufactured to the exact material and dimensional specifications required for a proper combustion seal. This part carries the same Multiquip part number 12251ZF1800 used in the original assembly, so there is no guesswork on fitment. DHS Equipment stocks this gasket as a direct replacement to get your equipment back in service quickly.
Key Features
- Genuine OEM Combustion Seal Integrity — Manufactured to the precise material grade and compression rating needed to maintain cylinder head sealing pressure on Honda-powered Multiquip equipment.
- Drop-In Head Replacement — Matches the original bolt pattern and gasket profile exactly, seating cleanly between the cylinder head and engine block without rework.
- Broad Equipment Compatibility — Fits MVC90H plate compactors, WM70S/P mortar mixers, QP205SH centrifugal pumps, MC64P/S concrete mixers, MP-series masonry saws, and additional Multiquip models sharing the same Honda engine platform.
- Prevents Compression and Coolant Loss — A correctly seated cylinder head gasket maintains the combustion chamber seal that keeps the engine running at full power; a failed gasket causes compression loss, overheating, and oil or coolant contamination.
- Fuel System and Engine Safety — Proper head sealing prevents combustion gases from entering the oil system, protecting against engine damage and reducing risk of uncontrolled oil burning or exhaust leaks.
The cylinder head gasket forms the critical seal between the engine's cylinder head and the engine block, containing combustion pressure and preventing oil or coolant from entering the combustion chamber. On small Honda-powered equipment like Multiquip compactors, mixers, pumps, and saws, this gasket endures extreme heat and pressure cycling every time the engine runs. When the gasket fails — whether from age, overheating, or improper torque — the engine loses compression, runs rough, overheats, or begins consuming oil, all of which quickly sideline the machine if left unaddressed.
