Multiquip 12251ZH7800 Cylinder Head Gasket

The Multiquip 12251ZH7800 is a genuine OEM Cylinder Head Gasket designed for a wide range of Multiquip, Whiteman, Essick, and STOW equipment including plate compactors, concrete mixers, walk-behind power trowels, and diaphragm and centrifugal pumps. As a direct OEM replacement sourced from Multiquip, this gasket is manufactured to the exact specifications of the original component. Confirmed fitment includes MVC64, MVC82, MVH-R60, MC-42S, CA4, CA90749, QP2H, QP-204H, MQ-D206H, and many additional models across the Multiquip equipment portfolio.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact material grade and compression specifications of the original gasket, ensuring a proper combustion chamber seal without leakage or blow-by.
• Direct Drop-In Replacement — Matches the original head bolt pattern and deck surface profile for straightforward installation without machining or shimming.
• Broad Multiquip Fleet Coverage — Fits plate compactors (MVC64, MVC82, MVH-R60), concrete mixers (MC-42S, EC-42S, WC-42S, CMS-4S), walk-behind trowels (CA4, CA4HM), and diaphragm and centrifugal pumps (MQ-D206H, QP2H, QP-204H, CP-20H), making it a practical stocking part for mixed fleets.
• Compression Retention — A correctly seated cylinder head gasket maintains engine compression and combustion efficiency; a failed gasket causes oil or coolant intrusion, hard starting, and loss of power output across all equipment types this part serves.
• Combustion System Safety — A compromised head gasket can allow combustion gases to escape toward fuel or oil passages; using a correct OEM-spec replacement eliminates that risk and keeps the engine operating within design parameters.

The cylinder head gasket forms the critical seal between the engine block and the cylinder head, containing combustion pressure and preventing engine oil or coolant from entering the combustion chamber. On compact equipment like plate compactors, mixers, trowels, and pumps — where engines run hard in demanding site conditions — the integrity of this seal directly determines engine efficiency and longevity. When a head gasket fails, symptoms typically include a drop in compression, white or blue exhaust smoke, contaminated oil, and overheating, all of which will sideline the machine until the gasket is replaced.
