Titan 700-793 Plastic Piston Insertion Tool for Pump Rebuilds
Titan 700-793 is an OEM plastic piston insertion tool (also called a piston guide tool) designed to simplify and protect the installation of the piston assembly during pump rebuilds on a wide range of Titan airless sprayers and line stripers. It is listed in official Titan manuals as a recommended service tool included with packing grease for pump servicing. The tool provides a smooth, tapered surface that compresses new seals gradually as the piston is guided into the cylinder bore. This prevents O-rings and packings from rolling, nicking, or tearing—a common cause of premature pump failure and leaks. It also ensures the piston enters the cylinder straight and evenly, preventing scoring of the bore and misalignment. The 700-793 is compatible with a broad range of Titan models, including the Epic 690 HPG, 660 HPX, 660ex, 447 HPX, 447ex, Impact X series, Airless Sprayer 690 GXC, 660 XC, and many others. Service technicians should always use this tool when installing a new piston or rebuilding the pump to protect new seals and ensure a long service life.

The 700-793 Plastic Piston Insertion Tool is a direct replacement service tool for compatible Titan sprayers. To use: lubricate the new piston seals and the inside of the guide tool with the recommended lubricant. Slide the piston into the tool, ensuring seals are seated against the tapered lead-in. Hold the tool squarely against the face of the pump cylinder and gently push the piston through the tool and into the bore. The taper compresses the seals evenly and guides them smoothly. Never force a piston into a cylinder—if it does not slide smoothly, stop and re-check seal orientation, lubrication, and tool size. Clean the tool after each use and store in a clean, dry location.
