Leaking under trigger could be the ball seal part # 875645 if leak starts as soon as you connect the air hose. If no air leaks when you connect hose but begins to leak when you depress the trigger then replace the oring on the plunger which is part # 874820. If air leaks when you connect the hose and the ball mentioned above is good then most likely is leaking from oring # 876161 installed on cylinder plate (remove head and pull out the plate). Good luck.

My D51822 nail gun blowing air where nails come out. what do i need?


Dewalt framing nailers use about 6 vinyl orings that fail. These orings are yellowish in color and turn into a soft mush allowing air to leak. Replace with buna (black rubber) for long life. If air leaks out nose, replace two vinyl orings at the bulkhead and one in the head. If air leaks from the trigger valve, replace vinyl orings on the trigger pin. Good luck with your repair

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

It depends on which model and where it is blowing air from. Some models had a replaceable trigger valve assembly and also head valve assembly. The SKS model is like this. Go to Toolpartsdirect.com and with your model number you should be able to find a parts diagram.

Model 734 1/2 in impact.wont blow air ,wont rotate,no tension on trigger.feel like problem may somehow be in trigger housing....


Yes, if you take it apart you'll find that the trigger isn't allowing air to pass through to the veins of the impact wrench. It's a relatively simple mechanism, where maybe something is broken inside.

If it were blowing air but the veins were stuck, I would say, lubricate it. But, if no air goes through it at all, then the trigger housing houses the problem part.

Have you tried to disassemble the air wrench?

If the trigger still works to fire the single shot, then the o-ring kit should be sufficient. If the trigger area continues to leak air, then the trigger should be replaced as well. Keep the gun well lubricated as well.

Duofast ms 7664c staple gun still blowing air out


This series of nailers are the most difficult to repair. Your nailer has twice as many orings as the norm. Many have said that this nailer is over-engineered. There are three areas that could cause trigger area leak. To make it simple, lets do one area at a time. Use soapy water around the trigger area to find actual leak. If air is leaking from actual trigger valve (ms719-2) and its counterpart, the cartridge (ms719-1) then these two parts need to be removed. Check for scratches in the metal of the valve. If scratched try to remove with fine paper or replace as necessary. Most leaks are due to faulty trigger valve. If air is not leaking from actual trigger valve then remove the dump valve (mn120-5) at the back of the head of gun. There should be two small allen screws then metal lid, then spring and oring. Pull out dump valve and make sure all the orings are in order. This valve should be able to move, not too tight. Use silicone paste lube on all orings (available at Lowes in plumbing department, Danco brand used for faucet orings). Reinstall dump valve and related parts and check for leaks. If air seems to be leaking from bottom of gun neer trigger, most likely problem is cycle valve (mm419-1) and related vinyl seat. These two parts are in the valve housing under the trigger. This valve also moves within its housing and seats on a vinyl oring. This part could be clear vinyl or black rubber. New seats are clear. Inspect these parts for scratches/cuts and lube with silicone paste. Hopefully you would have solved the problem with trigger valve. Good luck with your repair and do not dispare, this is one of the most difficult guns.
