The dive shop that filled my 88 cuft scba tank the last couple of times had their adapter stolen. They said they weren't going to buy a new adapter anytime soon, but if I brought one in they would fill my tank. The chat guys at Pyramyd didn't know what adapter to recommend. What adapter do I need to go from my Air Venturi HP4500 SCBA Valve to DIN. Also where do I get it?
