Does anybody know the threads on the bottle? It looks like they come with M18x1.5 male Inlet thread or 5/8-18UNF thread. I sold this bottle to a friend a couple of years ago and he hardly used it. I'm going to sell it for him but I think it needs a new fill station, The open / close valve has to be tightened down extremely tight to keep it from leaking and I want to identify that to the future owner. Here is a picture of the bottle, The Omega bottle is sold.
