Edgun Leshiy Leak===> I give it up finally

Are you refering to the presure relief screw? (Bleeder)
If so you can get a different screw and epoxy it in to seal it perminently. 
But that would be a last resort.

Hopefully Ed or Brian at EdgunWest can help you out?

Email me i can fix that for you.

I said before and I'll say again, no screw should be directly in contact with constant pressure in a pressure vessel. Bleed screws should only see temporary pressures (ie transfer port)...

For what it is worth here is my take on leaks through the bleed screw. I think that leaks can occur when the downward pressure on the spring that forms a contact with the ball bearing causes the spring to slip over the bearing instead of pushing it down to form a seal. This seems to me as poor engineering or simply just not the best way of making a seal. It has to be just right to form a good air lock. My solution which works perfectly for me is to use PTFE tape to form the barrier between the screw and the ball bearing. Do not wrap the tape around the screw but rather just sandwch the tape between the screw and the bearing. You need to judge the correct amount of PTFE tape but this is easily done by making a firm bed between the screw and ball bearing but not too much that you can not tighten the screw firmly enough so that the head of the screw is flush with the face of the hinge.

I dont know if anyone else has suggested this because I have not followed all the links on this or other websites but if you have not tried it then why not give it a go. I have found that doing this not only creates a tight seal but you can also open and close the bleed screw and it will still function as intended albeit the air will escape a little slower than with the spring solution. This is no issue at all. 

If anyone wants to follow this up with me I will be happy to answer any questions.

It is not, right? The screw is holding a steel bb ball in place to seal off the bleed hole. But as this seems not an ideal solution either, another option that was offered to me was;

to cut off a small length ( a few millimeters is all you need) of o ring that fits in the screw hole and compress it with the bleed screw (which is simply a metric grubscrew). I used this and it works fine. As the small pice of oring “tube” will be compressed by the screw the thickness and length of the cutoff piece is not critical.

Hello,

in the method I described the bleed screw would not be in direct contact with the sealing ball. In fact as far as I can tell your solution is the same as mine except instead of a piece of O ring It would be padded in between with a ‘layer of compressed PTFE tape. Note I said sandwich the ptfe between the bleed screw and the ball bearing not wrap the ptfe around the screw thread. The ptfe retains its elasticity similar to your solution.
