Bubbler airlock for use in demijohns and brewing bins.
An old favourite, single piece bubbler type airlock for use when making beer or wine.
7 in stock.
An old favourite, the bubbler airlock is ideal for beer and winemaking. Air locks prevent air getting into your brewing vessel and spoiling the must/wort, and allow the escape of the carbon dioxide (CO2) built up during primary fermentation.
Add a small amount of sterilising solution or cooled boiled water and place in a bored cork/bung or a grommet and use to seal a brewing bin, demi-john or wide necked fermentation vessel.
Air locks can be also be used in place of solid bungs to seal demi-johns or fermenting vessels for long term storage.
Please note: The bubbler DOES NOT come with a bored bung.
