Problem with Concave Pin Valve Depressor

[Bagheera]

I just received an inline gauge, which I planned on using to connect the co2 tank to. However, upon receiving it in the mail, I realized that the pin valve depressor is concave, not convex. What does this have to do with the pin valve? Well, because the depressor is concave, it's barely depressing the pin valve on the co2 tank, not giving me enough air. So, what are some possible solutions for this? One I could think of was to add some of the liquid metal mix (the kind that uses two different tubes to bond together), less than a drop, thereby turning it convex. However, would this hold up to the usage of depressing and relieving the valve on the tank?


Here is the item I purchased, and I would like to use it.

If you roughed up the depressor before you put on some jb weld so that it had something to hold onto, it might last. You could add a small piece of brass in the middle for wear. However, you might have to dig it out of your airlines or reg body some day.

The nice thing would be drill and tap the inside of the depressor for a small set steel screw that you blue loctite in. That way if you get a bottle with a longer pin, you can adjust it.

That's another possibility I considered. I can also go all the way through, and use a very small machine screw on the other side, and use plumber's tape to air seal the threads. Then I can tighten like a @#$%^&* and not worry about stripping threads.

Thanks. I wasn't sure if anyone else had the same idea, or if I was just crazy.
