Frequently Asked Questions

No. The 17P185 Triax Replacement Pump is for corded handheld units only (Ultra/Ultimate/TC Pro corded). Cordless models use a different pump assembly.

It fits: Ultra Handheld Corded (17M359), Ultimate Handheld Corded (17N162), and TC Pro Handheld Corded (14N163).

The 17P185 is a drop-in module. Depressurize, remove the old pump, seat the new cartridge, and follow sprayer priming steps. Most users can perform this quickly with basic tools.

Use tips and materials approved for your corded handheld model (see your sprayer’s manual). Tip size and material compatibility are governed by the sprayer’s specs, not just the pump.

Filter your material, use the correct tip, clean immediately after use, and store per Graco guidelines. Regular cleaning prevents premature wear of stainless steel/carbide components.
