5 x Solid Rubber Bungs by Almost Off Grid.

5 x solid rubber bungs with no bored hole. Rubber bungs are used in homebrewing to prevent air and contaminants from entering the fermentation vessel.

Each rubber bung fits snugly into the neck of a standard-sized glass demijohn. Ideal for wine, mead and cidermaking, and all kinds of fermenting. Solid stoppers can be used to seal a demijohn after all fermentation has finished, allowing the contents to clear and mature in bulk rather than bottling straight away. 

5 x standard sized solid bungs in each pack.
