"O" Ring for SCBA Tank/Valve?

DadsKrag · Apr 16, 2021

I ran across a good deal on 45 min SCBA tanks W/O valves and valves from another source in "excellent condition". SCBA tanks manufactured in 2010. I might purchase 2 of each.

The valves do not have "O" rings. Is there any special specification for the proper "O" rings?

I use the metric 22 x 3.5 mm orings. For the 4500 psi tanks I'm pretty sure the 90 duro are the correct ones.. Non metric is usually 2-014 (thin) or 2-114 (thick). Depends on your oring groove tolerances.

Buy a kit called “save a dive” on amazon. It’ll have the tank seals included in the kit.

Not coming up with anything relevant with "save a dime" on Amazon. Could you post a link please?
