Help to ID this adaptor

This adaptor is used by a local fire department to fill SCUBA tanks from their compressor that they normally fill SCBA on. Can anyone ID the thread size on the end of this pressue checker/Yoke assembly? I am not that familiar with SCBA fittings. It's kind of like a reverse DIN ?

Bryan, that is 1/2 an old USD cyl pressure guage. The thread is the same as any pressure guage you can get from GRAINGER.

I know about the pressure gague side but I'm wondering about the thread size where it connects on the other end? I'm trying to help someone with this ID so I don't have it right in my hands to measure by.....Anymore ideas?

It looks to me like a standard oxygen tank fitting. As in the large storage tanks. It is similar (or identical) to the fittings used by most air cascade storage tanks.
If it is what I am thinking, most commercial gas suppliers or welding suppliers should have that fitting.

I think Luis is on the right track but there are different sizes for different gases. N2 and 02 cylinders use different valves and I believe the valves on air cylinders from the commercial gas suppliers also are different.

Rob. I believe this is the female to the male filler adapter in your picture. It is used to fill Scott scba cylinders.

The picture didn't work. I'll try again.
See if these work Tom
