Almost Off Grid Pack Of 5 Rubber Bungs To Fit Demijohn - Bored/With Hole suitable for homebrewing Wine, Cider and Meat, Reusable

5 x Bored Rubber Bungs to take bubbler airlocks. Suitable for use with standard glass 6 bottle/1 gallon demijohns. The pack includes 5 top quality bored rubber bungs for homebrewing. Simply fit the airlock (not included) into the pre-bored hole of the bung. The rubber bung creates an airtight seal in the neck of the glass demijohn. Air then is released through the hole in the bung and into whichever separate airlock you choose to use: bubbler, handy or s-shaped. This set up allows air to escape but prevents contamination and fruit flies entering the brewing vessel.
