Where it fits & how it’s used: Install on Graco Hydra-Cat plural-component systems to refresh the lower pump section that takes the brunt of wear.

Installation tips: Always de-pressurize and flush your unit before disassembly. Inspect the rod and cylinder for scoring, replace damaged hardware, and lubricate new packings per the service manual. Before returning to work, function-test the system’s pressure relief valve and perform a low-pressure leak check.

Get the most from your rebuild: A refreshed pump performs best with the right gun-side setup. Pair this service with clean filtration, correctly sized airless spray gun tips, and ergonomic paint sprayer guns to keep patterns crisp and rework low.
