Hey folks.

Does anyone know if a regulator intended for medical use will work on one of those tanks from the hardware store? DO they both use left-handed threads and have a post valve?

The reason I ask is because I already have the tank, line, and stone. I just need the regulator. I decided to check on ebay, and there are quite a few O2 regulators on there for both welding and medical use.

There are some really compact ones for medical use that would cost about $10 (that includes the shipping), but I can't see in the pictures if they have the same sort of connectors needed to hook to a regular welding supply O2 tank.

Depends on the regulator. Most O2 regulators used in the medical profession don't have a "right or a left handed" thread. They simply slip over and tighten onto a poppet on the tank (sorry if I'm not describing this correctly).

I have a medical O2 tank (of course, I use it for medical use on my squad truck), but I have been known to "think" about using it for oxygenating beer.

Medical O2 regulators are also quite expensive--- $100+ (on average) for a "cheapy"

Medical and industrial regulators are very different critters.

You're doing fine... that totally made sense.

I figured there had to be something different, but wasn't sure.

I'll just spend a couple bucks more and get one that I know will work.

Thanks!

Let me tell you what I know from working with LOX (liquid O2). There is no oil in any O2 tank period. If there was you would not be around to talk about it. Liquid O2 is quite safe now gas form O2 now that dangerous. Gas O2 over any petrolium product is about as big a BOOM as you can make.

I got my o2 set up last week and brewed with it sunday. Cut my lag time by 24 hours when I used dry unhydrated yeast.
