Regulator for commercial oxygen tanks?

[gravityspiral]

I read an advertisement in an issue of Brew Your Own magazine that I threw away, for a company that sells regulators (and tubing/stones) that you can hook up to commercial oxygen tanks. I have my old oxy/acetylene torch hookup from back when I used to do HVAC and am interested in repurposing my oxygen tank for this... the only problem is no matter what search terms I use I can't seem to find the company that makes/sells it.

Anyone use this or know where I can find it?

Update: I should have been more patient. I tried one more variation on my search and finally found it.

I have one of these and it works great. I got a full O2 bottle at a local welding shop for $65, and I bet I've used less than 5% of it over the last 30 brews.

I also did HVAC (15 years) and I do use my old O2 torch. I just shove the tip of the torch into the tubing that is connected to a O2 stone. Works great, and easy to disconnect.

Doesn't the o2 tank already have a regulator on it?
