Fusion FX CS air piston kit with o-rings, Graco Part 2001166


This is the CS air piston kit for the Graco Fusion FX spray gun, supplied with o-rings. The exploded diagram is explicit that it comes without the dosing piston and without the safety stem, so it is the version to order when you already have those parts or are replacing them separately.

It fits the Fusion FX in the CS configuration. If you would rather do it in one go, Graco also lists a complete CS air piston assembly for the FX. Check the exploded diagram before ordering, as that is the quickest way to confirm which of the two matches the work in front of you.

Genuine Graco OEM part 2001166.
