- Selling Unit: Each
- One piece 2 Chamber airlock that features a smaller chamber so you can closely observe the CO2 rising and with that, the rate of fermentation. Fill the airlock with water and insert into a drilled stopper to vent gases during fermentation.
- Airlocks enable CO2 to be released during fermentation, but it traps oxygen from entering the fermenter and harming your beer or wine. Choose between the Bubbler Airlock and the Three-Piece Airlock. Compatible with all our drilled stoppers.
