You have some worn or broken o-rings in the gun and you need to replace them to fix the problem. If the gun is over two years old I strongly suggest you replace all the o-rings. Unfortunately Bostitch does not make an all-in-one repair kit with all the o-rings you need. You have to go to www.bostitch.com and on the left side of the page click on the 'schematics and parts' link. Type in your model number and you'll get a list of all the available parts for your gun. At the top, a schematic pdf is available so you can have a picture of what parts go where. You can order the parts directly from Bostitch or shop around, the parts are reasonably priced on their page.

Hitachi 45ab blowing air out of trigger


If air leaks thru trigger as soon as you connect airline, replace the vinyl ball under the trigger stem. If air leaks when you depress the trigger, replace the small oring on the trigger stem. If air leaks slightly from plunger in front of the trigger valve, problem is inside of the gun. Remove the head and pull the large circular plate. Replace the large outer oring. Good luck

My husky framing nailer leaks air around trigger


Leak around trigger could be trigger valve internal orings or orings on the outside of the trigger valve making contact against the body of the gun. Spray soapy water to determine where the air is leaking from. If air is leaking around the outside of the valve, most likely the orings were cut upon installation of the valve. If leaking from internal valve, most likely worn or broken oring; easy to fix if you have a source for orings.

To remove the trigger valve for service or inspection (take close-up photo of trigger area for reference ):
disconnect airline, remove nails, remove trigger retainer pin, remove trigger, remove roll pin /s holding trigger valve in place (use 3mm punch to remove retainer roll pins which are located in the body of the gun just above the trigger valve). With retainer pin/s removed and with gloved hand (under trigger valve), apply air pressure to gun to blow out the trigger valve (use lower pressure to push out trigger valve because it could come out with force.). With trigger valve in hand notice that there are two slots or groove cut neer top of the valve where the retainer pins rest, you will need to reinstall valve into body with slots aligned to retainer pins. Remove retainer pins holding trigger together to pull out internal valve. Good luck and post again if your have other question about the trigger valve.

Hitatchi nv45b2 trigger leaking


Air leaking around the trigger area could be caused by vinyl ball / gasket under trigger valve bushing or orings within the gun. Easy test, remove nails and connect air (assuming that air is now leaking around the trigger area). Depressing the trigger stops the leak, replace vinyl ball. Depressing trigger does not stop leak, move plunger b (plunger B, small shaft under bubber bushing next to the trigger valve) with your finger in then out to determine if air leak changes tone. If air leak changes sound or tone, then air is leaking past orings of the cylinder guide and/or cylinder plate and/ or the cylinder itself is scratched by debris where the orings make contact. Pull out the cylinder and examine the contact areas. If scratched, use 300 grit paper to smooth, if smooth, however, suspect the orings of cylinder guide (or cylinder guide is cracked). The cylinder guide is difficult to remove and install without causing damage to guide or cutting new orings when installing. Do not remove the guide unless all the other options have been checked. One last bit if information, I have noticed that some guns will leak air if the orings on the feeder piston do not fit snuggly. Make sure that leaking sound is not coming from feeder area (remove the basket and feeder/feeder pin/spring and pull out the feed piston, making sure that the largest oring is making good contact within the cylinder). Good luck with repair.

My hitachi roofing gun leaks air from trigger when not pressed


Two areas to check when air leaks from around the trigger. Rubber ball under trigger pin will cause air to leak, however when good side of the ball falls on the seat, air will not leak for a while. If air is leaking from plunger pin (just in fromt of the trigger pin), remove the head and pull out the cylinder plate to reveal broken oring (oring part # 876161). Good luck with your repair project.

How do i fix my triger leaks


Unfortunately, trigger leaks are only fixable by replacing the trigger mechanism. Can you update this with the make and model? I should be able to direct you to a parts location. Trigger assemblies usualy run around $20 or so.

My dewalt framing nail gun was hooked to the air compressor, but was not being used when it began leaking air which you could hear and got louder. It sounded like it was leaking around the trigger area....


There are O-ring seals around the trigger that are probably leaking. You can try to lubricate the gun by adding the pneumatic oil to the air supply. That may be enough to seal it back up. Otherwise the seals and/or the trigger assembly will need to be replaced.

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.
