Anyone know what this fitting is called? Used on 1500 PSI gas line.

Anyone know What this fitting is called? Just the male end.
It's on a CO2 tank line. 1500 PSI maybe.
Big end is CGA320 for Gas Tank.
Little (male) end has a flare on the end but threads into a 1/8 NPT fitting just right.
That would make it 27 TPI.
Used to seeing a flare like that on JIC fitting. Not an NPT.

See image.

Thanks a bunch

There are many, many families of flare fittings out in the world, many with SAE threads.

Good head start would be to measure the seat angle of the flare, then accurately measure the threads (diameter and pitch) and then call Parker or whomever you buy fittings from and start searching for a match.

It looks like a female connector.

Looks like somebody tried to make a dual-function fitting- it can be threaded into a female 1/8" NPT fitting with thread sealant- as long as that fitting is deep enough that the tapered end doesn't bottom out before the threads tighten!- or used with a female nut and a flared tube.

I second the suggestion to measure the threads, but the image looks very much like the thread is tapered. It could be an optical illusion though- measure it to be sure. If it is indeed tapered, it is NOT for use with a female threaded flare coupling nut. If not tapered, it should likely NOT be used in a female NPT fitting, even if it seems to fit...

It looks like the stem for a pressure regulator.
The CGA320ft is the tank valve and the NPT threads into the regulator body.

Looks like a taper lock. There must be more to the fitting assembly. The part pictured has no wrenching flats to use to tighten the seal cone feature.

Thanks folks. It came out of a aftermarket gas line adapter kit from Korea.
EdStainless got it right I think. Smart.
I should have given more details.
It screwed into a big steel body (cylindrical) only used as a T.
I bet the body was a regulator part used for a different purpose.
It's tapered for sure. I will use teflon goo and good torque and should be fine with NPT.
I think it's just a custom part.
Great forum. Bunch of smart, sensible engineers here. (not talking about me!)

Thanks
