Yep it's the trigger valve. I would disassemble clean everything good and grease all o rings and housing before assembly and I mean apply light grease liberally to where the o rings have to slide in. They like to roll and leak. Take your time do it right. Put the pins on the trigger valve in and test it to see if you got it. If so then put it all back together.

Prolly clogged, buy a rebuild kit and use it making sure all parts are totally clean before reassembly. in the future be sure to drain your compressor at least daily after use (more on wet or humid days) to avoid this

Bostitch just blows air when trigger is pulled


Air leaking from trigger when attempting to fire the gun is normal and should cause nailer to fire, however if the trigger pin is not depressed all the way in,the gun may not respond. Easy test. Remove the nails and remove the trigger. Connect the gun to air and quickly depress the valve pin all the way in with finger. If the gun fires, adjust the safety foot so that the trigger pin is depressed all the way in. If the gun still does not fire, then remove the head cap and pull out the headvalve. Apply plenty of white grease to orings and retest. If the gun fires, then replace the headvalve orings. When the headvalve orings are worn, air will leak from bulkhead chamber to the headvalve chamber causing the gun to not respond to the trigger. The addition of grease to worn orings will make them temporarily seal. 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 N80S stick framing nailer that leaks air from the trigger area. I replaced the entire trigger valve with a new single fire trigger to see if the old bump fire trigger was the problem


Remove the nails and take off the trigger to expose the trigger valve (usually part # tva6). Connect air and spray soapy water on the valve to determine if the air is leaking from the center of the valve or around the outer edge between the body and valve. If leaking from the center, could be defective valve or debris under oring. Pop out the valve and examine internal parts for cut oring or defect. If leaking from between body, you could have cut orings installing the valve. Make sure that there are no rough edges in the body of the gun. Bump fire or single fire happens with the trigger type not the valve. Bump fire trigger is usually black metal and single fire trigger is light color plastic. Good luck

I put a new o ring rebuild kit in my Bostitch N80 sb framing nailer. I replaced every o-ring (including the trigger valve assembly


If the new trigger valve leaks air when you connect the air supply, most likely defective valve or air is leaking past outer trigger valve orings due to debris in the slot or new orings were cut when the valve was pushed in. If air leaks when you depress safety to fire gun then most likely problem is in the head valve or safety foot is not pushing the firing pin all the way in. Easy test, remove nails and remove the trigger to expose the firing pin. Connect air and very quickly depress the firing pin all the way in. If the gun fires, adjust the safety foot as needed. If the gun does not fire, remove the head and check headvalve orings for good snug fit against the cylinder within the head. The surface were orings make contact must be very smooth and not too deeply worn. If you notice fine scratches remove with fine sandpaper. Reinstall head using plenty of white grease on all the orings within the head and retest. Good luck

There are about three issues with this gun that could cause your problem. The safety contact arm not depressing the trigger pin fully, worn trigger valve (tva6), or leaking orings in the headvalve. Easy tests. Remove the nails, and remove the trigger to expose the tva6 valve. Reconnect air and with very quick and firm action, depress trigger pin all the way in. If the gun fires, adjust safety foot and trigger so that the trigger pin is depressed all the way in each time that you fire the gun. If the gun does not fire, remove the head and remove the headvalve. Examine the surface/s where Orings make contact with magnify glass looking for fine scratches. Sand with 400 grit paper. Orings must make good contact here or gun will not fire. Lube orings and surface with silicone paste lube (sold at Lowes in the plumbing department or swimming pool supply store). If no fine scratches and surface looks smooth, replace Orings in head and the tva6 valve. Good luck with your repair/

Bostitch RN46 will not fire nail, only releases air when trigger is held and firing tip is touched to surface of material. Any ideas on what is wrong?


Gun will not fire if air is leaking past orings in head /headvalve or safety /trigger is not pushing trigger pin all the way into trigger valve. Test: Remove trigger to expose trigger valve pin. Remove nails. Place nose of gun against thick rubber mat or coiled rubber hose to absorb blow of driver. Very quickly and deliberately press trigger pin all the way in. If gun fires, safety foo or trigger is not pushing trigger pin all the way in. Make adjustments or replace worn parts. If gun still does not fire, remove head and pull out headvalve. Apply lots of silicone paste lube on the orings and the surface of the head where orings make contact. Reinstall head and test as above. If the gun fires then orings were leaking. Replace orings and sand any scratches on body of cap with very fine sand paper. Parts are at www.toolpartsdirect.com Good luck

Stanley bostitch double fires. It is an older stick feed. Works fine when I hold the trigger and tap the tip. But when I press the gun into the wood and pull the trigger it double fires. Gun is older, but...


You did not list your model number, however most bostitch nailers use the tva6 trigger valve. As this valve wears it will be erratic. Examine the firing pin that makes contact with trigger. If it looks worn or wabbles from side to side, then time to replace. To remove valve first remove trigger by removing roll with 3MM punch. Next remove one or two roll pins just above the valve, also 3mm. With roll pins removed air pressure will pop out valve. Be carefull because valve can come out with force, use glove or rag to catch. Parts available at www.toolpartsdirect.com, or generic valve at www.ebay.com. Good luck

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.

Air leak on framing gun


You can repair this gun. Parts and breakdown are at www.bostitch.com look for service /parts and enter your model number. There you will the parts available for purchase. You will need the tva11 trigger valve. Easy to install. Remove roll pins that hold trigger and trigger valve. Remove the trigger to expose the tva11 valve. With the roll pin/s removed that hold the trigger valve you will be connecting air supply. Use heavy glove to catch valve as you apply air pressure. You may reduce pressure to airline to reduce pop-out force. Before you install the new valve check port for sharp edges and debris. Good luck with your repair.
