Paslode t250 f16 leaks air from the cap difuser

All air gets out from top sometimes as soon as air supplied and as soon you pull trigger. Do i change all inside orings and seals or total rebuild?The gun has not used every day just on side jobs for seven years.

The most common problem with this nailer is the plastic seal that sits on top of the cylinder. This seal (ususlly white, yellow or black in color ) will cause the nailer to leak lots of air out top of gun. Examine seal for cracks and replace as necessary; the part number is 402725 and is available at This should stop the rapid air leak. After installing the new seal, if you have a very small constant leak out top of the gun then remove the screw holding the headvalve in place and check for small scratches where the orings contact headvalve. Use very fine sandpaper (300 to 400 grit) to remove scratches. Clean and re-use the same orings using silicone grease instead of oil and re-assemble. This should stop all leaks. Silicone grease is available at Lowes lumber in the plumbing department. It is used to lube orings in faucets. If you have more questions about this gun please email, Good Luck

Several things to check for piston not returning to top of cylinder. Most common problem is bent/ broken driver. Worn oring on piston is second most common. Piston should move easily in cylinder but hold in place. Point nose of gun up then down again, if the piston moves within cylinder, replace the oring. Lower bumper and washer with slot under the bumper must be in good condition. If the bumper is cracked or missing pieces and or if the washer fits too loose around the driver blade, the piston may not return to top. Finally, pull out the cylinder and make sure that the check-oring is in place around a series of holes on the middle to lower part of the cylinder (small groove cut into cylinder with several small holes). Good luck with your repair

My paslode t250-f16 doesn't fire when triggered-- only feel air coming from around the trigger

When headvalve orings are leaking, the nailer will not fire. Remove head and also remove the headvalve. Examine the surface/s where orings make contact looking for scratches. Sand surface with 300 grit paper until smooth. Reinstall parts using silicone paste lube. If head is too scratched /worn, also replace with new including orings as needed. Good luck

Paslode f350s.just replaced all o rings,now when you pull the trigger air leaks out through the trigger,but only when depressed..will not fire nail.please help ..thanks bob

Simple. You have a leak you didn't have before. Either find it, or take it to someone who knows what they're doing. O-rings have a thickness, as well as a diameter. If you used generic rings, that's probably the problem. Use the repair kit by Paslode. can tell you where your nearest dealer/repairer is.

T250S-F16 16 Gauge Straight Finish Air Nailer i have an air leak out of the front of the gun where the driver comes out and makes contact with the nail head (the hole tri-shapped hole) It only leaks after...

Air leaks from the bottom of nailers are due to leaking oring /s that seal cylinder to body of gun and/or leaking thru seal at top of cylinder where headvalve seats. Remove head and examine sealing surfaces of headvalve and top of cylinder. Must be smooth, then pull out cylinder and check oring/s that contact body of gun. Remove any fine scratches on inner body with fine paper (400 grit). Lube with silicone paste. Good Luck!

Paslode 5350 90s

it sounds like it needs cleaned. Paslodes are a dificult gun to take apart and clean yourself, I would find a local shop that services them and pay the $50 to have it cleaned.
