Fermentation airlocks are an essential addition to your home brew equipment. They allow you to keep air away from the homebrew beer or wine but also allow excess carbon dioxide to to escape from the fermentation vessel.

Fermentation airlock is a standard size (17cm/6") and will fit any standard vessel. Fermentation bubbler is fits snugly in the bung and in the grommet. Bung is 32mm at the top and 16mm at the bottom.
