This is a genuine Bostitch replacement part that fits all BT brad nailers and all S32 staplers. If trigger leaks air or if tool misfires often, try replacing trigger valve. This kit contains one (1) each of: valve assembly (including both O-rings), lubricant, spring pin punch, and repair instructions. Please note that two (2) O-rings are included but can also be purchased separately as parts # 106967 and # 86459. O-rings are easily damaged and worn out, causing tool issues, so it\\\'s a good idea to have a backup or two on hand. Only a hammer is needed for this repair.

2.Removed trigger and spring.
3.With pin punch removed pin that held trigger valve in place. Didn't drive either pin completely out but drove out just far enough to remove trigger and trigger valve.
4.Removed trigger valve by using a small awl to force out. Instruction say to hold rag over it and hook up to air and let it force it out but it came out without any problem using awl. I wasn't worried about damaging valve since I was going to be replacing it anyway.
5.Lubed new valve assembly, cleaned trigger housing and checked for burrs, and reassembled
in reverse order.
6.Works like a new gun. Complete repair including tear down took less than 30 minutes.
