The 0551509 Lower Seal Packing Tool (direct replacement for Titan 762‑202) is an OEM‑spec installation tool designed for the pump cylinder on compatible Advantage, Impact, RentSpray, and SprayTech airless sprayers. It is used to drive lower packings and seals into the pump bore without damaging the sealing lips or the cylinder wall.
Attempting to install lower packings with a screwdriver, socket, or improvised tool often rolls, cuts, or misaligns the seal, leading to premature leakage, pressure loss, and pump failure. The 0551509 tool has a precisely shaped nose that guides the packing squarely into place, protecting the seal and ensuring a reliable, long‑lasting repair.
