This 2-micron stainless steel air stone threads onto the side port of the X-Series Uni Flex Chamber, allowing you to quickly oxygenate or carbonate wort, or purge the Flex Chamber of oxygen when dry hopping. You can leave the air stone in place during filling and fermentation, and easily connect gas via the Ball Lock Quick Disconnect.

Avoid touching the stone with bare hands, as the oils on your fingers can cause clogging issues. We recommend sanitizing and blowing gas through the stone before and after each use.
