As DAAGC states the threaded fitting on both tanks/regulators (propane -acetylene, and for many other gasses ) is a industry standard CGA 510 style connector... For oxygen its a CGA 540 style connector....

New propane tanks with OPD valve also have external threads for larger ACE thread fittings...

Hose connectors are, for oxygen CGA 022 (b size) and for fuel gasses CGA 023 (b size) ....

And if you notice, the notches or groove cut in "wrench flats" in fitting signify a "left hand" (counter clockwise ) thread....
