Air Stone .5 Micron

Description Attach 2' of 1/4" tubing from the 'gas in' dip tube inside the keg. (Tubing not included). You set your desired pressure on the regulator and gas gets emitted through the .5 micron stainless stone. The half micron bubbles rise through the beer and are absorbed, creating a carbonated beverage. The .5 micron stone has smaller bubbles and a faster absorption rate than the 2 microns.
