Repacking Kit for RentSpray & Spraytech Airless Sprayers
The 0551533 Repacking Kit is an OEM seal and packing kit designed for the pump fluid section of RentSpray 400 and Spraytech Advantage EPX2155 / EPX2255 airless sprayers. It includes all the wear‑prone elastomeric components needed to restore hydraulic sealing when the pump loses pressure, fails to prime, or leaks past the piston rod.
Over time, piston packings harden, O‑rings crack, and backup rings deform. A repacking kit addresses these common failure points without replacing the entire fluid section. Using the 0551533 restores consistent pressure, reliable priming, and extends pump life.
