Titan 0551536 Piston Assembly for Pump Pressure Restoration
Titan 0551536 is a complete OEM piston assembly that includes the piston rod and pre-installed packings or seals, ready to install directly into the pump cylinder. It is designed for the fluid pump of compatible RentSpray 400 and SprayTech Advantage EPX2155, EPX2255, and GPX80 airless sprayers. A worn or damaged piston rod can cause pressure loss, poor priming, erratic spray, and accelerated packing failure. Replacing the entire piston assembly restores proper rod surface finish and correct geometry, ensuring reliable pump performance without the need to transfer old packings. Bedford Precision offers an aftermarket piston rod assembly (SKU 57-2770) as a direct replacement for Titan 0551536.
