It's a very simple regulator with an outlet for co2 tubing. I guess you can say it's a on/off valve with an outlet for co2 tubing.
I think making an adaptor is the only solution. Where can I buy a CGA-320 replacement valve? How do I contact a machinist? How do I look for a machinist? If I was looking under Yellow Pages, what is it under? You can find a machinist at a machine shop right? I know these questions are dumb but I have tried for a few days now, trying to solve this problem. I am having trouble finding a machinist. Should I go to a welder instead? Please help.
