This stainless air stone on a 22" stainless steel tube is ideal for aerating wort before fermentation. Features a .5 micron air stone that is permanently affixed to a 22", 3/16" outer diameter stainless steel wand. Fits standard aquarium air pump tubing. Easy to clean by soaking in diluted Star San solution or by boiling for 5 minutes. The stone is 1/2" wide by 1" long. Quality made in the United States, the stone on this wand is press fit without adhesives and is sturdy enough to be boiled if needed without damage.
We recommend this finer stone when you are using compressed oxygen, and are aware that the fine pores require more thorough cleaning than our 2 micron Aeration Wand, which is easier to blow through and easier to clean.
