Leaky Xvalve

do you have a RT on/off or a ULT?

If you have shims in the powertube, remove them.

[VecTor]

Sorry, RT on/off and no shims.

[OPBN]

Oil? Its amazing what a few drops can do.

[nak81783]

Replace black outside diameter carrier oring with one from a carrier you'll probably never use. Sometimes those get damaged when pressed by the threads.

Unlikely be that as he said that he had tried different carriers.

Yup. Oversight on my part.

[VecTor]

Yea when I looked at exploded view of x-valve chart I thought of that too but each carrier has its own oring
Agreed on the oil part. I can tell when i forget to oil as it doesn’t RT as well when it’s getting dry.
Now it’s been a while since I have changed any orings in the entire valve (gotta love mags for that reason alone) is there other orings that could be a prob due to age?

[BigEvil]

Do you have a #0 carrier? Try it, fresh orings, a little oil, no shims.

How are you removing the powertube internals?

I've ruined brand new powertube orings in one removal using the field strip screw. I now use a dull 90 degree oring pick. I make sure the pick is on the Teflon washer, and pull everything out together. I guess what I'm saying is try another new powertube oring, and be careful removing it when you size the carrier.

As far as other orings, probably not, since your velocity is consistent and there are no other leaks, but I've made a lot of otherwise unexplainable problems go away by changing the orings on either side of the brass reg seat holder.

I do but at carrier with 1 line I was bolt sticking a lot and still leaking. I soaked the new oring in oil and worked the bolt on the valve.

You might have to increase the velocity a bit to overcome the bolt stick until the oring breaks in. Using smaller carriers might make your velocity drop some...

[VecTor]

Well that makes since didnt even think to check speed again.

[need4reebs]

try loosening or tightening the field strip screw to see if that affects tha leak at all? and maybe check the on/off o-rings...especially tha lil small one that you have to unscrew the on/off top and bottom to get to?
