3-Piece Airlock
This three-piece airlock is the best choice for fermentation needing an oxygen-free (anaerobic) environment, such as beer, wine, mead, sauerkraut and cider.
Also known as a fermentation bubbler, bung, or air trap, it enables CO2 to be released during fermentation, while keeping oxygen and bacteria from entering the fermenter.
Easy to use, the airlock securely protects your fermentation from contamination.
To use, simply fill with water or alcohol up to the "Fill line" level and insert into the drilled lid of your fermentation container.
The three pieces are easy to disassemble and clean.
