leaky valve

[Anvari]

my x-valve has a bad leak between the power tube and the valve body. any ideas on how to fix this?

[OPBN]

Are you saying between the two halves of the body? If its coming from the tiny hole on the left side of the body it is probably some dirt or something on the reg pin.

Maybe a pic and a pointer as to exactly where it's leaking.

[Anvari]

Its leaking at the seam between the silver and black pieces

[OPBN]

Hmm. Thats not good. However, there is an O-ring that sits inside there. Not sure if that is one they sell though. You may want to contact Tunaman.

You'll have to send it in to get fixed or find someone with the know-how and that won't mar up your valve in the process. They take special orings that AGD doesn't sell to the public.

Do they screw together or pressed?

Screw.

How do you know its leaking from that specific joint? Its sometimes hard to tell where a leak is coming from when the valve is installed in the body.

I am having a similar leak or so it feels like it. Is there a way to test the valve out without having it installed on the body?

[athomas]

There is no way to test this outside of the body.

You can narrow down the leak area. Hold the trigger in when you gas the valve up. If it still leaks, then the problem is not where the powertube meets the valve body. It is in the regulator part of the valve or on-off area.

There have been some leaks from the powertube/valve joint, but it is very rare. When the valve is installed in a metal body, quite often leaks sound like they are coming from one area when they are actually coming from somewhere else. It takes some maneuvering and careful listening to determine the nature of some leaks.
