Rubber bung 48/44 mm

A necessary supplement to the demijohn is a properly fitted rubber bung with a fermentation tube or a cork stopper. The plugs are provided with an opening in which a fermentation tube (glass or plastic) can be mounted. Made of PVC.

Synthetic plugs for demijohns - it is recommended to wash them thoroughly with warm water and washing-up liquid before use, then dry them thoroughly. This is to remove the layer of silicone left over from the manufacturing stage that may cause the cork to slip out of the demijohn during fermentation or slip off in the case of rubber hoods.
