Your nailer most likely uses a trigger, and the best place to purchase a new trigger is amazon. Take a look on this link Bostitch TVA11 Trigger Valve Kit I hope this was helpful. cheers

Your nailer most likely uses a trigger valve part # tva6 (cost about $25) and is sold at www.bostitch.com or ebay for generic. If you have a source for orings, you could try to repair the valve. Remove the roll pin that holds the trigger to expose the tva6 valve. There are roll pin/pins that hold the valve in just above the valve in the body (Use punch for 3mm hole). Remove these pins and apply air pressure to gun to pop-out the valve. Use caution when you do this. Remove nails, lower pressure to gun and use glove or rag to catch valve because it could come out with force. Note the two grooves on the side of the valve where retainer roll pins hold valve. Remember to insert the valve with these two groves aligned with path of roll pins. With tva6 valve in hand remove two pins that hold valve together and remove inner plunger. The middle oring/seal on plunger is cause of leak. Try using an oring with smaller inside diameter than the broken or loose fintting seal that is present. It must fit pretty tight and be slightly thicker than 1/16" to work (metric 5.3 x 2.5 works). Remove the outer orings to valve and clean and re-use same. Clean the valve port in body of gun and check for sharp edges to prevent cutting orings before inserting the valve. Use silicone lube or oring lube on the orings and the valve port (Danco silicone paste sold at Lowes in the plumbing department). Good Luck on your repair and email if you have other questions

SOURCE: I need help replacing a bostitch framing air

follow closely, do you have a new trigger assembly because the problem is with one o ring commonly referred as the purple o ring in the kits? either way the procedure to remove the trigger is first knock out the roll pin for the trigger latch and then the 2 roll pins for the trigger assembly. next get a shop rag or equivelant and place under the now exposed trigger assembly and then while holding the collar on the air chuck plug into tool and hold rag tight and trigger will "pop" out pull the chuck away and remove the 2 pins to disassemble the assembly or install in reverse order lubricating the o rings first. Let me know if you have any questions or problems.

N88 bostitch nailer fires when connecting air hose


I have seen this on dewalt nailers also, caused by trigger valve worn. on Bostitch nailer part # tva6 remove roll pins retaining trigger and trigger valve. one roll pin for trigger and one or two for valve. With pins removed apply air pressure to gun popping out the valve. Use glove or folded-up shop rag to catch the valve as I pops out. Be sure to reduce air pressure as it could come out with force. Good luck

N88rh bostitch nailer fires first shot without trigger depressing


Worn orings in the gun and the trigger valve will cause the gun to fire upon connecting the air. It is a good practice to remove the nails when you remove the airline until you can replace the trigger valve. I believe that you gun uses a TVA6 valve. It should be replaced when it begins to leak or if the trigger pin seems loose and rocks from side to side. Factory valve costs about 25 dollars and aftermarket sells for about 12 to 18 dollars. Good luck

I have a Bostitch coil framing nailer M#N80CB-1 which was working fine one minute, than after setting it down for a minute it is leaking air under the triggger and will not fire after the first nail.


Air leaking at the trigger is caused by faulty orings in the trigger valve. You could replace the orings in the valve or replace the whole valve (not expensive on ebay, look for generic tva6 valve usually less than $20). Good luck

What causes air leak around trigger and loss of compression on bostitch on n79ww modelframing nailer


Are you using air tool oil fairly frequently? Any rubber "O" rings will wear rapidly if not lubricated properly.

Framing gun not firing leaking air aroung trigger


You have a crumbled trigger seal. You can order a new trigger valve through bostitch. It usually takes a couple of weeks though.. Every time I order one it is on backorder. You will need to order trigger valve kit part number TVA11 $21.40. Go to the Bostitch website click on Schematics and Parts to the left then find your model nailer in the search field and select item 53 when the parts list comes up. Click add to cart to order. Another screen will pop up and ask you if you want to checkout. Any questions please post back.

Constant air leak


Sounds like you need a repair kit or take to a tool company that installs the kit.
