The 249125 piston rod is one of the most common displacement rods used on Graco's contractor grade electric airless paint sprayers.
The piston rod connects the internal parts to the motor and gear box. The rod moves up and down with the action of the drive system and motor. Fluid is loaded on the upstroke and displaced on both the upstroke and downstroke. Displacing fluid on both the up and down strokes ensures an even flow of fluid to the hose and gun.
