Part 118594 is an o-ring for the Graco Fusion FX spray gun. Graco's exploded parts diagram lists it as an o-ring and it is supplied singly, so you can buy the exact number you need for the job in front of you.
Seals are the reason a rebuild either holds or leaks, and they are the last thing worth economising on when a gun is already in pieces. If the gun is open, fitting a fresh o-ring costs very little next to going back in later.
Work from the position on the Graco parts diagram and order against the part number so you get the correct ring. Genuine Graco OEM part 118594.
