A demi-john rubber bung is a stopper that is used to seal a demijohn during the brewing process.
Demijohn bung is typically made from rubber and fits snugly into the mouth of the demijohn to prevent air and contaminants from entering.
The demi john bung also allows for the attachment of an airlock, which allows carbon dioxide to escape during fermentation while preventing oxygen from entering.
Bored bung means you can use a Bubbler Airlock with the bored rubber bung
