A faltering pump or cracked fitting on your Graco Ultra Max II 495 PC stalls production, chews profit and bruises deadlines. Our website warehouse keeps every OEM component—from the Chromex™ Endurance Pump lower to the tiniest seal—on the shelf. The factory-spec 246428 pump restores the original 0.60 GPM @ 3300 psi performance that makes the 495 PC Pro the “sweet-spot” rig for repaint crews who need big-sprayer muscle in a 34-lb frame.
