Trigger Valve Assembly

OEM part for: Bostitch, DeWALT, Porter Cable

Part Number: TVA6

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.
