The Multiquip 12391ZE2020 is a genuine OEM Cylinder Head Gasket designed for a wide range of Multiquip, Whiteman, and Essick equipment powered by Honda small-block engines. This gasket provides a critical combustion-chamber seal between the cylinder head and engine block, and is a direct-fit replacement confirmed across models including MC94P/S, MC64P/S, MC12PH, WM70S/P, WM120SH, WM120PH, MVH208GH, MVH308GH, MVH408GH, V305EH, MRH800GS, AR13H, AR13HC, GAW180HE, QP402H, QP3TH, SP118, MP2H, and GA9.7HE, among others. Sourced directly from Multiquip, this part carries the same OEM specification as the component installed at the factory, so you know you are installing the correct part the first time.
Key Features
- Genuine OEM Head Gasket Material — Manufactured to Honda engine tolerances, ensuring the correct compression rating and combustion seal integrity for small-block Honda applications across the Multiquip product range.
- Drop-In Engine Replacement — Matches the original bolt pattern, bore diameter, and thickness of the factory gasket, allowing straightforward head removal and reinstallation without surface rework.
- Broad Multiquip Fleet Coverage — Confirmed fitment across concrete mixers (MC94P/S, MC64P/S, MC12PH), Whiteman mortar mixers (WM70S/P, WM120SH), plate compactors (MVH208GH, MVH308GH, MVH408GH), rollers (AR13H, V305EH, MRH800GS), pumps (QP402H, QP3TH), saws (SP118, MP2H), welders (GAW180HE), and generators (GA9.7HE, GA6HEB).
- Combustion Integrity Under Load — A correctly seated head gasket maintains cylinder compression and prevents coolant or oil from entering the combustion chamber, keeping the engine running at full power output during demanding jobsite use.
- Emission and Pressure Compliance — The OEM gasket maintains the designed combustion chamber volume and sealing pressure, supporting proper engine emissions performance and preventing pressure-related damage to the head or block.
The cylinder head gasket forms the primary seal between the engine's cylinder head and the engine block. Its job is to contain combustion pressure, prevent combustion gases from escaping, and keep oil and coolant passages isolated from one another. When a head gasket fails — typically from overheating, age, or improper torque — the engine may lose compression, consume oil, run roughly, or overheat rapidly. Replacing a worn or blown head gasket with the correct OEM part like the Multiquip 12391ZE2020 restores proper sealing and protects the engine from secondary damage caused by contaminated fluids or lost compression.
