This type 304 stainless oxygen stone features a 2 micron stainless diffusion stone, coupled to a 1/4" male hose barb, to fit any 1/4" interior diameter tubing. This works with oxygen and fish tank type air pumps. 2" long, 1/2" wide.

Note: Our Q11 Oxygen Regulator does not fit this, as its hose barb is smaller than 1/4"

Poor Workmanship
I use the stone for carbonating. The joint between the barb fitting and the stone was not sealed properly, so relatively large bubbles emit from the joint, compared to the desirable small bubbles from the stone. I had to seal the joint with epoxy to get the stone to work properly. 

William's Brewing Responds:  It sounds like you received a defective stone. We are sending a replacement out no charge. Sorry for the problem with this.

Works well
I have tried this and the .2 micron stone. This one works better as it doesn't clog as easily.

I found that you need a good pump for this to work properly, but when it does , it really gets the yeast going nicely.
