Frequently Asked Questions

It houses and guides the piston shaft inside the pump fluid section, allowing smooth movement and consistent fluid pressure during spraying operations.

No, this part is designed for industrial and heavy-duty Graco pumping systems rather than small residential sprayers.

Replacement is recommended if there is visible scoring, internal wear, pressure loss, or reduced pump performance.

Installation usually requires partial disassembly of the fluid section. A full rebuild is not always necessary, depending on pump condition.
