| Help identifying this cylinder please.
I picked up this never used cylinder off ebay from a Military Surplus store, advertised as a rebreather O2 bottle, originally thinking of using it for drysuit inflation. When it got here, I realized it had a tapered thread, and not a standard 1/2" NPT that most threaded scuba cylinders used. It appears to possibly be a 3/8" NPT, or maybe a BSP pipe thread. A 3/8" NPT hose barb threaded into it, but felt very sloppy. The cylinder pressure rating is 2850+, and it has both DOT and TC stamps, and was manufactured by PST. I emailed the surplus place I got it from, and he has no idea what military this would have been used by, but the DOT and TC stamps made me assume it was North American.
Can anyone help me identify A: what military would have used this and in what rebreather? and B: are there commercially available valves for this, or should I just scrap it and get a cylinder with a regular 3/4 NPSM O-ring?
Thanks,
Jim |
