All of my disconnects are already threaded, this would fit perfectly in line. I've been cleaning out my system (well 2 systems, kegerator and jockey box) and it seems that the check valves at the distributors haven't been working that well, all of my air distributors have gunk in them, as well as a reg, and I don't know how I managed to do that. Needless to say a lot of my gas lines did too and are being replaced. I was hoping this could prevent that from ever happening. And I did check, the valves I had operate as check valves when I blow in them.
