Itme Q11 Oxygen Regulator
Work fine. The regulator did exactly what I wanted it to, ie turn the can of oxygen on and off. I do wish the control knob was made of metal vs plastic, but for this price something had to be compromised. Again excellent product, excellent service from the folks at Williams Brewing

An economical way to build your own oxygenator
After looking at several different oxygenation kits, I found this valve to go on a disposable O2 tank that I got at the hardware store. With a 3’ section of tubing and a .5 micron air diffuser my own kit was complete. I just tied the diffuser to the long end of a brew spoon, turned on the air and gently stirred the bubbles into my cooled wort. After getting the best and most active fermentation ever...I’m a total believer in oxygenating the wort with pure O2. I could never get enough O2 into the wort by just shaking the fermentor.

Works Well
Does what it's supposed to do.  Fits well on a Bernzomatic O2 cylinder, remembering it is left threaded.  Aquarium tubing fits well, too. Just does its job nicely, without excessive spillage and hazard.

Great regulator and great price
The regulator is well built. It's smooth to adjust to get a gentle flow.  

Note that the hose barb is not removable and is 3/16", whereas most carbonation/oxygenation stones have 1/4" hose barbs. 

You can force a 1/4" hose barb into 3/16" hose, but its very difficult to remove then. You can use a hose clamp and probably get a good seal, but there's a good chance it'll leak.  What I did is buy a nylon hose coupler (Menards sells them) for 1/4" hose and then force it into the 3/16" hose on the regulator side, and 1/4" hose on the other side to the stone.
