    As a commercial hard hat diver we would wear a 50# bail out bottle in case our hose supply got pinched off . Does anyone know if this can be converted over to CO2 for the keg system >?

    I am going to go out on a limb and say "probably not". The tank cares less what gas is used, but the connectors are the problem.

    For a keg system you really want a CO2 regulator which is threaded in a way to only attach to a CGA320 valve (the top valve stem in the tank). The male part of the CGA320 which is attached to the main body of the tank uses a 0.825-14 NGO-RH-EXT thread which is pretty much unique to CO2 cylinders. I am guessing your bail out bottle used air or some other gas compatible with human life. Scuba threads are almost always 0.750-14 NPSM. The question is what are the female threads in the neck of your tank, that's what will determine compatibility.

    The gas industry makes its connection in a way to prevent commanality. My experience is this is pretty much across the range of gasses. They want it to be impossible to put an argon regulator on a nitrous oxide bottle, or an oxygen reg on a scuba tank. Sometimes inconvenient, but potentially life saving.

    BTW, nice Mark V rig.
