The Multiquip 2791500123 is a genuine OEM Head Gasket designed for G-4.5R, GA4.5R, QP3TE, and QP-40TE series equipment. As a factory-sourced component, it meets the exact material and dimensional standards set by Multiquip for these machines. This part is a direct replacement for the original Head Gasket, ensuring a correct seal without the guesswork of aftermarket fitment. Confirm your model code before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact compression rating and material grade specified for the original engine assembly, ensuring a consistent, leak-free seal under operating temperatures and pressures.
- Direct Drop-In Replacement — Matches the original bolt pattern, port layout, and thickness of the factory Head Gasket for straightforward installation without rework.
- Broad Model Coverage — Compatible with G-4.5R, GA4.5R, QP3TE, and QP-40TE — covering both portable generator and trash pump applications powered by the same engine family.
- Engine Performance Protection — A properly seated Head Gasket maintains combustion chamber pressure and prevents coolant or oil from entering the cylinder, keeping the engine running at full power output.
- Fuel and Emissions System Compliance — A failed or weeping Head Gasket can allow combustion gases to escape, affecting emissions output and posing a safety concern; using the correct OEM gasket restores the engine's sealed combustion integrity.
The Head Gasket sits between the engine block and the cylinder head, forming a critical seal that contains combustion pressure while keeping engine oil and coolant in their separate passages. When it fails — whether from heat fatigue, improper torque, or age — the engine loses compression, may consume oil or coolant, and can suffer irreversible internal damage if left unaddressed. Replacing a worn or blown Head Gasket with the correct OEM part restores proper combustion efficiency and protects the engine from further wear.
