I have never seen a connector like this... Any idea?

It looks like a face seal fitting. There's an o-ring in the face of
the mating fitting.

looks like some one just put a blow off valve into an NPT fitting, that or
an
adapter of some sort. i would bet money that piece will come out and you
will
have a standard fitting

Inlet side?
Have you ruled out CGA-320?

I was going to say CO2 , my adapter for the MIG looks just like that .

Those CGA fittings are often stamped with the CGA number somewhere on the
fitting, though they can be a bit devious. Yours looks like it might have
used a flat washer of Teflon or similar material as a seal.

My experience with CO2 regs supports that statement.

Flat like that looks like CO2 to me.

I was under the impression that CO2 only maxed out at something like 320
PSI in the tank. No?

Notice the reading of the high pressure gauge?

My CO2 tank is sittin' on 700 PSI at 65*f and my guage goes to 4k . This
regulator set is the Lincoln add-on for the small wirefeed welders , and is
also intended to be used with other shield gasses ... I'd hook up the C25
tank and see what pressure it's at , but I'm lazy .

Hmm ... the gauges have "use no oil" on them, which suggests
that they are for Oxygen. I don't think that I would want any kind of
washer (other than annealed copper perhaps) on the high-pressure side of
the regulator.

Enjoy,
DoN.

In the UK currently about 230bar IIRC or about 3300psi on a full
cylinder. PITA when they uprate the pressure and your old regulators are
no longer suitable.

Hummm...I may well be wrong. Frankly..I seldom ever pay attention to
the CO2 high side gauges on my Mig rigs..just the low side.

Anyone?

The fitting looks nothing like those for oxygen in one of the links I posted
earlier. Maybe the original fitting was changed out.

That would not fit on an oxygen tank with the flat surface. Oxygen requires
the fitting that has what looks like a nipple the size of your little
finger. Argon, too. Argon CO2 too too.

As an afterthought, I retract that. The flat surface on the regulator MAY
fit flatly against the flat outside ring on the valve body of an O2 tank,
but be sure to use a flat fiber or teflon washer. Just have to try it and
see. It will either work, or it won't.

^^^^^^^^^^^^^^^^^^^^^^
I don't see why a CO2 regulator even has a high side gauge. The tank
pressure is related to temperature, not fullness, as long as there is some
liquid present. That's also true of propane and butane, and that's why
weigh the tanks, or resort to tricky methods to know what you have. One
method is to look at the frost line while the gas is being used.

^^^^^^^^^^^^^^^^^^
However, it does look a lot like the fittings on medical oxygen tanks. They
use a flat Teflon washer.

I think it is for mounting the regulator to a manifold system, like at a
production shop or a school.
Several torches piped to same source.

I have a single stage acetylene regulator with the same kind of fitting.
If you check the threads it probably fits 1/2" straight pipe threads.
