Part 248136 is the back cap O-ring for the Graco Fusion AP and Fusion PC spray guns, supplied as a bulk kit. Graco's parts list describes it as an O-ring, cylinder cap, package of 6.
On the exploded view it appears under the same generic "O-ring" label as the other seals, so work from the callout number rather than the description. Confirm your parts diagram points to 248136 before you order.
The six-pack is the practical way to buy it: one order covers this rebuild and the next, and the seals are genuine Graco rather than a generic substitute picked by size. Genuine Graco OEM part 248136.
