Set of 2 airlocks for home brewing. Comes with demijohn bung and a grommet so you can use these with a fermentation bucket or a demijohn. Plastic air lock, as opposed to a glass air lock can take heavy wear and tear which prevents beakages. Fermentation airlocks are an essential addition to a home brew equipment.

They are ideally sized to fit a demijohn. The grommets fit a standard 12mm bore hole in the fermenter lid. This wine airlock and rubber bung will ensure perfect results every time; keeping airborn bacteria away from your wine, cider, mead or kombucha. It is an essential wine making equipment and mead making kit. Fermentation airlock is a standard size (17cm/6") and will fit any standard vessel. Fermentation bubbler fits snugly in the bung and in the grommet. Bung is 32mm at the top and 26mm at the bottom., Weight: 2.645547144E-4 pounds, Manufacturer: Brewing Mate
