Maintain & Upgrade with Precision-Engineered Graco DutyMax GH230 HD Pump Parts List (24W999)
DutyMax GH230 HD puts gas-powered muscle behind Graco’s Endurance™ lower, feeding block filler, asphalt emulsion, and fibered roof coatings at up to 2.0 gpm and 3 300 psi. When a belt squeals, a packing weeps, or a seat chips, the whole rig grinds to a halt—and your crew’s payroll meter keeps spinning. That’s why rental yards, municipal striping departments, and commercial roofers rely on SprayersAndParts for factory-serialized rods, packings, belts, check balls, bearings,control panels and any graco accessories. Each kit is bench-tested, heat-sealed, and shipped the same afternoon you order, complete with torque specs so you can finish the swap in the time it takes for the compressor to cycle.
Why Choose Genuine Graco DutyMax GH230 HD Pump Parts (24W999)?
