What regulator is this

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.

Here are some references:

Flat like that looks like CO2 to me.

My experience with CO2 regs supports that statement.

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?

Pondering on this for a moment..I believe I am wrong. I think I was thinking about propane tank pressures.

Cringe...sigh....somedays I get most everything right..but they are rare.

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.

Steve

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.
