I bought this over a year ago but it started not holding air for long, so it got thrown in back of safe. Any suggestion or disassembly advice?
No it won't even take air to find leak. Going to take it apart and reseal.Do you know where it's leaking from?
If you want help, you have to do better in answering the questions asked. We have a lot of experience with this gun, but you are there and we are not. You have to be our eyes. Taking the gun apart and resealing can cause as many issues as those that you can fix. This is especially true with the regulator. It is best that you do this very carefully. Shotgunning a problem is not a good troubleshooting method, because you learn nothing. Submerging the gun in water will not hurt the gun if properly dried afterwards and is a great way to identify the source of the leak.No it won't even take air to find leak.

Agree 100%.. I took my gun apart once and replaced all o-rings and when all was said and done it leaked from 2 different places that it wasn't leaking from before.. just try to identify the present leak and stop there.. I have a pp700w that's leaking from the fill port as we speak.. I've already done that o-ring change before so i know what it entails and I'm stopping there..If you want help, you have to do better in answering the questions asked.

Should this work?

Thank you for making the water test. This is a factory problem. The cause is an under size "O" ring. I created a thread on this issue a couple of years ago. The Band-Aid is a gasket like MrP said, but the fault is ITEM number 34 part number M10-054. The parts diagram says it should be an "O" ring 5mm ID x 1.5mm thick. It does not seal well because it is slightly too small. I tried a 5mm x 2mm and it shears on installing it, but a 4.5mm x 2.0 NPR70 works perfectly. Be sure to use a little silicone grease on the ring before assembling it. DO NOT disassemble the regulator. Just degas the tank and unscrew the tube. Always use silicone grease on all your "O" ring
