Is it for mixed gas? The cylinder connection is the reverse of what I think I need http://img16.imageshack.us/img16/5219/reg1n.jpg

not sure about the mixed gas, but if you read it properly it syas 'Oxygen' on it.

You are correct, for a standard pub CO2 cylinder you will need the reverse of that, a female connector.

That's an old medical oxgen regulator for 'J' size cylinders (huge tanks used as emergency O2 backup supply in hospitals / ambulances etc)
