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 ***

Tools Used:

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.

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.

Tools Used:

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.

Question: Air Leak In A Nail Gun

1499982

I have a stick type nail gun that is leaking air and will not fire. Do I need to replace the trigger valve assembly or is there something else that may be causing it?
WJA
Hello 1499982,

If it is leaking air at the trigger, the part number TVA6 Trigger Valve Kit, should take care of the problem.

-WJA
Question: RN 45

mike49

Is the RN46 trigger valve the same as RN 45. Part TVAC
WJA
Hello mike49,

The Trigger Valve Kit for the Bostitch RN46 Coil-Fed Pneumatic Roofing Nailer. Is part number TVA6.

-WJA
Is the TvA11 interchangeable with the TVA 6? I read that the metal cap on the TVA 11 was better for high use tools like my roofing nailer. Would that be a better choice than the ATV 6? I am replacing the stock TVA1 that is no longer available.
Hi,
No use the TVA6.The TVA11 won't work.Hope that helps.Good luck.
Tinker
Thanks for the quick reply.
Same valve in both tools . tva6.
Question: Trigger Valve

smbvb

Is there an easy way to remove the old valve?
Hi smbvb,
Remove the roll pins from the housing ,then grab the steam of the valve with a set of wire cutters.Grab it hard enough to get a good hold of it but not enough to cut the steam off.Once you have a good hold of it then just pull it out.Hope that helps.good luck.
Tinker
The best way that I've found to take out a trigger valve is to remove the roll pins and then take a rag and hold it against the valve. Now take your line from your air compressor and don't connect, but just bump it to your tool so the rush of air will dislodge the trigger valve. Just be sure to keep the rag fairly tight or the valve will squirt across the floor and under the workbench:p It works every time!

Question: Kit Trigger Valve

sonlor

Is their a breakdown of the valve parts? If so, is it possible to purchase only the inner seal gasket. I have a few valves with only this broken seal. Thanks
Hi there,
I'm not aware of a parts breakdown of the trigger valves. Bostitch does not sell the individual pieces to the valve. I hate to say it, but I'm sure they make way more money selling the complete valve assembly then selling that 5 cent plastic ring that always cracks on top of that valve:p
Gene
Hi genek: The TVA1, TVA6 and TVA11 can be fixed by replacing the broken or rotted ring with a small rubber o-ring,though I'm not sure what size. Also it seems to me Ebay sells little rebuild kits for the valves . Go out to your hardware store and buy a few o-rings close to the size and try each one to see if it works.I worked for Bostitch for a number of years and remember the service guys telling me how they fixed the valves this way. Hope this helps.good luck.
Tinker
No, the valve is rivetted together and cannot be taken apart. I wish it could. Once it's shot, they assume that the whole valve needs replacing, . Get one that's crimpped together, not the 2 piece valve with an upper part and a lower part, they will eventually separate. here at ereplacementparts.com, they sell a completely one piece white plastic, with a metal button, it's a good one to get, just like the old green bostitch TVA1, which is unavailable.

    The shipping took longer than I expected. I ordered on a Monday but didn't receive it until the following Saturday.

    easy repair

    Easy repair, fast fix less time than I thought!
    Part in perfect condition, and on top of that everything I need to do the job correctly was included a pin to push the roll pins out, and the o-ring grease added to my confidence the job was done right! Also quick delivery so I had my air nailer in working order to do the job I needed it for on time! Will be ordering another trigger valve kit for my roofing nailer shortly!
