Handy airlock for use in demijohns and brewing bins
An old favourite, two piece airlock for use when making beer or wine.
13 in stock.
An old favourite, the two piece airlock is ideal for beer and winemaking and can be used in tight or enclosed spaces when a bubbler type airlock would not fit. 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 gromet 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 airlock DOES NOT come with a bored bung.
