Description:
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.

Questions & Answers

Is this the trigger valve for a Bostitch N66C Nailer? Or is it common parts with N58C?
Belinda
Hi Belinda, Thank you for your question. This trigger valve is used for both the the Bostitch N66C and the N58C Nailers. I hope this helps. Thank you and have a great day!
TVA6 (trigger valve assembly kit) appears as replacement part for Bostitch F28 WW, but application specification only refers to brad nailers and staplers and does not include this model. TVA6 Picture does not look like valve in F28 WW. Will it still fit?

Trigger valve air leak and dirty nail gun
First thoroughly clean your nail gun [ I use various little brushes, compressed air, carb. cleaner, rags and then air tool oil ]. Set up an area with good lighting and work over a surface where you will not lose any small parts. "Cradle" the nail gun on some rags and carefully use a hammer and a small straight punch of the correct size to remove the roll pin that holds the trigger and its spring in place, next do the same to remove the roll pin that holds the valve assembly, make a bag full of rags as a "catchers mitt" - put this around the trigger valve location,put on safety glasses or face shield , briefly attach the air hose at less than 90 p.s.i. !!! [ start at a lower p.s.i. ], this should pop out the old valve assembly into your "catchers mitt". Inspect that the nailer is clean inside this opening, lightly oil this area, Apply a uniform thin layer of grease to the valve assembly then make absolutely sure that the new valve goes in "square" / straight to the opening and that the retaining pin hole lines up with where the roll pin must go back [ USE THE SUPPLIED ALIGNMENT PIN TOOL ! ]. Gently reinstall the roll pin, make sure the trigger and its spring are clean and reinstall these and the retaining roll pin that hold them. Of course visually inspect everything along the way : that new valve assembly is complete [ o=rings in place, no housing cracks in gun frame, no debris inside gun, etc... ]. *** using too high of air pressure to pop out valve during repair can hurt you or others - as it will fly out like a bullet or shatter plastic parts ***

Parts Used:
Trigger Valve Kit - TVA6
Repair Difficulty:
Easy
Time Spent Repairing:
15-30 minutes
Tools Used:
, Pin punch/Small hammer
Gun leaking air around trigger.
1.Took pin punch and removed pin that holds trigger and spring in place.
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.

Tools Used:

Air leak at the trigger.
Using a small hammer & a flat bottom punch, removed the roll pin holding the trigger in place. Using the punch again I removed the roll pin retaining the trigger valve,& covering the old trigger valve with a rag I hooked up the nail gun to the air supply & it popped out the old trigger valve into the rag. Using the supplied grease I lubed the o - rings on the new trigger valve & installed it into the gun, & then reinstalled the roll pin retaining the new trigger valve.

Time Spent Repairing:
Less than 15 minutes
Tools Used:
, Hammer
Air would leak passed the trigger assy and the plunger would not reset/return to original position.
I opened the package, followed the step by step instructions, used the long pin provided to push out the pins holding my trigger assy (I also used a hammer to drive/push the long pin - the instructions didn't suggest this.), used (some of) the packet of grease supplied, reassembled the tool with the new part and now everything works like a dream. Things took me longer because I'm a bonehead and took the trigger apart. Do NOT take the trigger apart - it has small parts that are assembled by people with 6 hands - a total PITA.
I will definitely use ereplacementparts again.

    Air Nailer Trigger Valve Repair Kit
    Part is a reorder of previous part I put in this gun. Problem is mine as the gun is not used often enough and seals dry out. ereplacementparts.com is a great place to find these unique parts in a timely basis. Added benefit is that you don't have to try to find a repair center or dealer who is 100 miles from where we live.
