Lower Packing Insertion Tool for Titan 740IX / 740I Airless Sprayers

The Titan 705-138 Lower Packing Insertion Tool is a purpose‑built service tool used during pump repair. It ensures that the lower packings (seals) are installed squarely and without damage into the pump cylinder. Proper packing installation is essential for achieving a leak‑free seal and maintaining maximum spray pressure.

Attempting to install packings without the correct tool can result in folded lips, nicked seals, or misaligned components, leading to premature pump failure, pressure loss, and costly rework. Using the 705-138 tool simplifies the process and helps extend pump life.

Service Tip: Always lubricate packings with compatible pump oil or light grease before installation. The insertion tool should be used with gentle, even pressure to seat the packings without distortion.
