This Bubbler Airlock with Rubber Bung (to fit 1 gallon demi-john) is the perfect solution for having an airlock on your fermentation barrel. The airlock allows the gas from the brew to escape without letting outside air into the vessel.

The fermentation process gives off a lot of gas which you can see and hear bubbling away, a good indication that your brew has finished fermenting is if it's stopped bubbling. Always be sure to check with a hydrometer though.

Dimensions of the Bung:

Height: 31mm

Narrow end: 28mm diameter

Wide End: 31mm diameter

Centre Hole: 6mm diameter

The colour of the dust cap may differ from that pictured.
