The O-ring behind the quick connect for the hose to the gun leaks. I replaced this oring and the leak stopped for about 30 minutes then started again. Do i need to replace all the orings in the unloader valve?

    The unloader vakve has a quick connect for the hose to hook to. when you unscrew the part behind the quick connect there is a part with there o-rings in it. the first oring is what is leaking. If i had a good parts break down i could discribe the parts better.

    A little confusing. Is your hose leaking where you attach it to the machine or where you attach it to the gun? The unloader is a part inside the pump itself. If it is where the gun attaches to the hose and a new o-ring (of the correct size) does not repair it you should check the Quick disconnects.

SOURCE: Honda 8HP GX240 willnot start after working fine.

Your carberator has crud, or rust, or glaze in it. The carberator will have to be removed, soaked in cleaner for three hours and then rebuilt using the proper carberator kit from any auto parts store. If you need to hire this done expect to pay about 35 dollars.

SOURCE: need new gun and connection to gun

The DuraBuilt and Coleman pressure washers have a gun that tends to leak through the plastic clyinder wall that holds the plunger that moves with the trigger. You won't see the holes, but if you remove the upper half of the housing, hold the plastic tubes in place with one hand and turn on the water, not the motor, you will see water shooting through the wall.

Amazon sells an exact replacement gun and hose. FAIP PowerWasher Replacement Gun and Hose #80012. Mine does not leak at all and was $29 shipped.

Make sure you DO NOT have a check valve (this is what stops your hose running when you disconnect from the hozelock fitting) in your hose pipe system, This will send a shockwave through the pressure washer and destroy the fitting you mentioned. They can be easily removed.

Dewalt D51822 trigger goes 1/2 way without depressing the piston. The result is the piston does not get depressed enough to fire the gun. Tried oiling piston, and goes to end of stroke--that is, fully...


Dewalt nailers use some orings that are made of vinyl (clear to yellow in color instead of buna or viton). These orings fail by getting soft and sticky. The gun may not leak but will not work correctly. The trigger should fire the gun when depressed about 1/2 way in. The oring repair kit has the same orings. I use generic orings in the gun to solve the problem. There are two orings inside the gun that should be changed and at least two on the trigger valve stem. In time the gun may fire a nail when you connect the hose. Check the internet for recall on some of these guns. The orings in the gun that should be replace make contact between the white cylinder spacer and the cylinder (smaller is standard oring # 141 the larger is 74.4mm x 3.1mm). The two rings on the trigger stem are 2mm x 1.5mm . If you do not have a source for orings then just replace the trigger valve. You also might try setting the depth adjustment all the way down. Good luck.

Bostitch N62FN air leaks out the cap and it wont pressure up or fire. Is the piston ring solid


Glad that you repaired your gun. The piston oring is the only oring in the gun that can have slit and still work fine. It works like a piston ring in a motor. Small ring gap is ok just as long as the piston does not drop down the cylinder under its own weight. The piston oring does not hold pressure, it only reacts to pressure when headvalve opens. When this series of gun leaks air, it is usually due to headvalve orings (lube with white grease), Cylinder seal loose or broken, or trigger valve oring splits (tva6 valve). 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

DeWalt D51823 nailer shoots continusously when plugged into air hoswe


Shooting continusously caused by worn orings in the trigger valve and in the gun.Dewalt framing nailers use some vinyl orings (gold or clear in color) that fail too soon in both the trigger and the cylinder spacer (white plastic). Air out the nose of gun indicates air is leaking past the cylinder spacer seals (If piston is pushed down with air leak then headvalve seal is leaking (remove nails for this test)). If piston is not pushed down with leak, remove head and pull out the cylinder with cylinder spacer (white plastic). Place the cylinder on workbench with bottom up. Push down on locking ring and remove retainer to release all the other parts. Take picture or take note of parts together and as you pull them off to aid in re-assembly. You will need to replace the two orings between the white cylinder spacer and the cylinder. Order oring kit from dewalt or just purchase one ( # 141 universal oring ) and one metric oring 74.4mm x 3.1mm from hydraulic parts store. If the piston was pushed down with air leak, replace headvalve orings in the head. The trigger valve also has vinyl orings on the trigger pin. You could try replacing the orings but hard to find . Pin uses 2mm x 1.5mm. The orings on the inner valve should fit snuggly on the outer contact surface. If the valve just falls out the the body, the orings are too loose or the body is worn. I would just replace the trigger valve to be safe, however repaired works ok if you can find the orings. Trigger orings do not come in the kit. I would also remove the nails after each use and only reinstall them after air is connected and gun seems to work as it should. The Good luck with your repair.

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.

I have a N59 FN air is leaking from the bottom of gun I put ne trigger and O rings still leaking now what.


Air leaking from the bottom of the gun (path of driver) indicates that cylinder seal orings are leaking (if without nails in gun the driver is slowly pushed down the cylinder when air is connected then cylinder seal is leaking ). Cylinder seal snaps on the top of the cylinder and should fit snug and have no cracks. Easy fix for cylinder ring. Remove head and pull out cylinder. Then remove the cylinder ring (part #n50015). Examine ring for cracks and replace as needed. Examine body of gun where spacer oring makes contact and sand fine scratches. Replace orings as needed. If air is leaking between body of the gun and nose casting, replace gaskets. Good luck.

Air leaks when triggered and no nail


Make sure no nails in gun. With air connected listen for leaking thru nose of the gun also. If leaking thru nose slightly, air is getting past the cylinder seal oring and/or top of cyl is not seating against headvalve. Repair leak to nose of gun before trying to fix head leak. With no air leaking thru nose of gun, add plenty of white grease to orings in the head (one oring at a time) to see if leak is less and/or grease will streak behind the leaking oring. Then repair as needed. May need slightly thicker oring or sand surface where oring makes contact to remove scratches that are allowing air to pass. Also air can enter the head thru the small port in the gasket leading to the head (make sure that the gasket is sealing).

The nail gun began leaking air from the nailer end so I dismantled it and found that the o-ring on the piston was broken so I ordered a new one and replaced it. However, once I put it all back together ,...


Piston oring will not cause gun to leak. Most likely the orings between the cylinder and cylinder spacer and orings sealing the cylinder spacer to the body. The cylinder spacer is the white plastic piece visable when you pull off the head. Order the oring kit and replace all the orings in the lower part of the gun. Dewalt used some vinyl orings on the cylinder that failed. The trigger also has orings that will fail. Good idea to order a trigger valve and have it ready( or replace now if the gun is several years old). Good luck and post again if you have question about this gun.

GUN DOES NOT FIRE FOR SEVERAL ATTEMPTS--even though gun is pressed firm against work---just had unit serviced and trigger valve replaced-----any suggestions? thanks joel


Remove nails and remove trigger to expose trigger valve pin. Place nose of gun against rubber pad or old coiled up air hose to absorb impact of driver and with very quick and deliberate motion press in trigger pin. If gun fires, then problem is with safety foot not pushing trigger pin all the way in (or worn trigger). Make adjustment as needed or replace faulty parts. If gun still does not fire, then likely problem is with headvalve. If headvalve orings are leaking, gun will not fire. Test for leaking orings as follows. Remove head and remove headvalve, apply silicone paste lube (plenty) to all orings and where orings contact. Assemble and do test above. If gun fires then surface where orings contact is allowing air to leak(smooth with very fine sandpaper if scratched).
