The Multiquip 14721Z5T000 is a genuine OEM Exhaust Valve designed for a range of Multiquip gasoline-powered generators, arc welders, concrete mixers, and walk-behind rollers. As a factory-sourced component, the 14721Z5T000 meets the exact material and dimensional standards set by Multiquip, ensuring a direct, like-for-like replacement in every compatible application. Confirmed fitment includes the GA6HB, GA6HEB, GAW180HE, GAW180HE1, GAW180HEA, MC12PH, V305EH, and MRH800GS. Sourcing the correct OEM valve by part number eliminates guesswork and keeps your equipment running at the performance level it was engineered for.
Key Features
- Genuine OEM Valve Material — Manufactured to the exact alloy grade and heat-treatment spec required to withstand the high-temperature, high-pressure exhaust cycle in Multiquip gasoline engines.
- Drop-In Engine Replacement — Matches the original valve stem diameter, head profile, and seat angle so it seats correctly without machining or shimming.
- Broad Fitment Across Multiquip Equipment Families — Verified for GA6HB and GA6HEB generators, GAW180HE series arc welders, MC12PH concrete mixer, V305EH walk-behind roller, and MRH800GS roller.
- Restores Full Compression and Engine Efficiency — A correctly functioning exhaust valve seals the combustion chamber at the right moment; a worn or burnt valve causes compression loss, rough running, and increased fuel consumption.
- Combustion System Integrity — Proper exhaust valve sealing is critical to maintaining safe combustion pressures and preventing hot exhaust gases from bypassing into the valve train.
The exhaust valve controls the release of burnt combustion gases from the engine cylinder at the end of each power stroke. It opens on the exhaust stroke to vent spent gases and closes tightly during compression and combustion to seal the cylinder and maintain pressure. Over time, exhaust valves are subject to extreme heat cycling and can develop pitting, burning, or stem wear — all of which degrade compression, reduce power output, and can lead to costly engine damage if left unaddressed. Replacing a worn exhaust valve with the correct OEM part, such as the Multiquip 14721Z5T000, restores proper cylinder sealing and returns the engine to its designed performance level.
