Your nailer uses a trigger valve (could be part # tva6 cost about $20, need to look up) and is sold at www.bostitch.com or generic valves sold on ebay . 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. 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. With tva6 valve in hand remove two pins that hold valve together and remove inner plunger. The middle oring on plunger is cause of leak. Try using an oring about same size as the broken seat. It must fit pretty tight to work. If you had a small leak it could be that the firing pin orings fit too loose or just too worn. Use silicone lube or oring lube on the orings and the valve port. Good Luck on your repair and email if you have other questions

Air leaking from trigger Bostitch SB1850BN


Most likely the orings or seals in the headvalve are not making perfect seal. Remove the head and pull out the headvalve. Apply plenty of white grease to orings and test again. If the gun fires, then will need oring kit soon, or just keep using plenty of grease. If the gun still does not fire, check that the safety foot is depressing the trigger valve all the way in. 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

SB1664 WON'T FIRE TRIGGER LEAKS AIR WHEN DEPRESSED


If the air is leaking from the trigger itself, the trigger asembly needs to be replaced. See the link below for more info about Bostitch repair info and cost. I would suggest that you closely examine the O-rings at the same time and chagne them if they appear worn.

I have a bostitch ridge runner that leaks air badly out of the trigger and wondering how to take out the plastic trigger in the gun. Also what would be the cause of the air leak


The air leak can be one of a few things. FIrst make sure that you have added some pneumatic oil to the air stream. This will lubricate the o-rings and make a tight seal. If that fails to resolve it, repalce the o-rings. (kits available for around $20). Next, woul dbe the trigger assembly itself. These triggers wear over time and are easily replaced.

See the website below for parts and a good diagram of the construction of the gun. You should be able to replace the parts by following the diagrams.

Please note that the exactmodel number is required to get hte correct diagram.

Hope this helps,
Dan

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.
