Set of 5 Fermentation Airlocks, 5 Bored Cork Bungs and 5 Solid Cork Bungs by Almost Off Grid.
Bubbler airlocks let CO² out without letting contamination in.
Just half fill with water and fit into the hole in the bored cork bung. This then fits into the neck of a standard glass UK demijohn creating a seal.
The Fermentation Airlock is a standard size so fits all Fermenters.
Solid bungs are used in demijohns when all fermentation has stopped. They are ideal if you wish to seal the fermenter before bottling, or bulk mature your homemade wine, cider, mead or beer in the demijohn rather than bottling at all.
The Bungs fit Standard Glass Demijohns.
Bung Size (solid and bored are the same size):
Top : 31mm
Base : 26mm
Cork bungs can be useful because they can be cut down to fit smaller-sized vessels, such as half-sized demijohns.
