This safety cork/bung is designed to fit into a demijohn once the fermentation has finished and you are waiting for your wine to clear / condition.
The safety cork/bung fits into the opening of the demi-john and allows any gasses to escape while preventing any air entering.
This is not to be used in place of an airlock while fermenting. This is for use only when fermentation has completed.
Use instead of a solid bung. This means that any excess pressure building up can escape and prevent your demi-john exploding.
This bung will fit a neck with a diameter of 28mm-30mm
