High Pressure Oxygen Valve.

New Mountain High, high-pressure oxygen valve with pressure gauge. This is no longer required as I have a different thread on my oxygen tank.
1.See Mountain High 00CYL-0020 DIN-477 Valves (https://wingsandwheels.com/mountain-high-00cyl-0020-din-477-valve.html). Depending upon which cylinder it is installed onto will determine the -01. -02, or -03 suffix.
2. The lower cylinder thread is 3/4-16 SAE-8. The outlet thread is DIN 477-9 (G3/4-14) BSPP (26.4mm OD).
3. The Valve is new but has a small scratch on the face of the pressure gauge. It is too small to be visible on the photos.
4. A burst pressure pressure plug is included on the case.
See Mountain High notes regarding their pressure gauges.
