Question re Valve for Emergency Medical Oxygen Cylinder

[rx7diver]

All,

I am considering using either an OMS (Faber) LP 46 scuba cylinder or an OMS (Faber) LP 66 scuba cylinder as a dedicated emergency medical oxygen cylinder. Whichever of these cylinders I ultimately choose, I will use it with a DAN Multifunction Oxygen Regulator, etc.

I intend to switch out the scuba valve for an oxygen valve. I have two choices: a medical oxygen valve (the post valve one usually sees on small, portable oxygen cylinders), or an industrial oxygen valve (CGA-540—the valve one usually sees on large supply/cascade industrial oxygen cylinders). I'm leaning toward the latter, since the medical oxygen valve seems to me to be more easily damaged, and the oxygen cylinder won't be protected any better than my other scuba cylinders when packed in the back of my minivan.

I'd like your opinions (with reasoning) re which is the better choice.

TIA.

Safe Diving,

How are you going to fit an oxygen regulator to it if it's got a supply-bottle outlet?

I'd stick either with DIN and adapt a SCUBA 1st stage outlet to supply a mask, or probably better is stick with the standard medical oxygen valve so you can regulate the output.

Either cylinder will do fine. There is no need to swap out the pilar valve. DAN sells a DIN to PIN index that allows a Multifunction Oxygen Regulator to be attached to a DIN/Yoke valve. They retail here for around $80-100.

gsk3,

DAN has two versions of its Multifunction Oxygen Regulator. The "standard" version (#611-2000, https://www.diversalertnetwork.org/store/home.aspx?id=37) fits the usual post valve, and the second version (#611-2100, https://www.diversalertnetwork.org/store/home.aspx?id=40) fits a CGA-540 valve.

Ajduplessis,

Your link doesn't work for me. Can you resend? (BTW, I see no such adapter on the DAN site https://www.diversalertnetwork.org/store/home.aspx?catNo=9.)

Thanks,

Didn't realize, sorry. I've only seen the one version.
