    Tried all the other ones I purchased for a rebuild but all too big. What size is the seal under the grub screw but above the ball bearing? Gun holds air great using the Robert Lane tester with the captive seal but the factory ring leaks like a sieve. Thanks!

    And also, just to confirm the order of assembly is ball bearing, then seal, then grub/retaining screw?

    Thanks!

    This is totally an educated guess as I dont know these guns but I would have thought its seal, ball bearing then grub screw.

    Agreed but they were out of stock until just last night. If the o-ring doesn't work out I'll order one.

    Ordered the part...can't hurt. I used 1.78x.1.78 but I've found conflicting reports that it should actually be 1.00x3.00mm. The quest continues.
