The Titan 700-793 Plastic Piston Insertion Tool is a specialized service tool designed to simplify and protect the installation of the piston assembly during pump rebuilds. It guides the piston and seals into the cylinder bore without damaging the delicate sealing surfaces or rolling the O-rings, which is a common cause of premature pump failure.
Using the correct insertion tool is essential for a successful pump overhaul. This tool ensures that the piston enters the cylinder straight and evenly, preventing scoring, seal distortion, or misalignment. It is compatible with a wide range of Titan airless sprayers and line stripers, making it a valuable addition to any service technician's toolkit.
