Healthy Safe Material:The whole 2 micron diffusion stone is made of SS316 stainless steel, which let our 2 micron aeration stone anti-corrosion Size:Male Connect 1.5" (50.5mm Ferrule OD Clamp) X 1/4" NPT
Carbonation Stones:made from SS316 stainless steel, these stones have a submersible porous body that diffuses CO2 gas directly into brewing liquid
Unique Carbonated Flavour:with 2 micron diffusion stone will produce smaller & finer bubbles which can make the O2 or CO2 combine with liquid faster
Specification:separation and permeation efficiency low filtration resistance and acid-alkali corrosion resistance environmental protection and non-toxicity
The Sanitary Fittings:best choice for our oxygenation stone is a useful this air stone to oxygenate wort and carbonate home brewing/soda prior to fermentation,works great for other drinks as well
