Check valve housing O-ring kit, Fusion AP/PC, Graco Part 248129


Part 248129 is the check valve housing O-ring for the Graco Fusion AP and Fusion PC spray guns, supplied as a bulk kit. Graco's parts list identifies it as an O-ring, check valve housing.

Because a Fusion gun uses several different O-rings and the exploded view labels most of them the same way, the part number is what tells them apart. Check the O-ring callout next to the check valve housing on your diagram and confirm it matches 248129 before ordering.

If you are already pulling the check valves apart, it is worth having the correct seals on the bench before you start. Genuine Graco OEM part 248129.
