Bubbler Fermentation Airlock
This bubbler-style fermentation airlock is designed to fit securely into a drilled cork or rubber bung, making it suitable for use with glass demijohns.
When brewing in fermentation buckets or plastic demijohns, it may be used in conjunction with a grommet; note that some vessels may require drilling to accommodate the airlock fitting.
To operate, fill the airlock halfway with water. This allows carbon dioxide (CO₂) to escape during fermentation while effectively preventing contaminants from entering your homebrew.
We have a wide variety of airlock styles available to suit different fermentation setups.
Please note: This airlock does not fit the white demijohn bungs
