About this range

An airlock lets fermentation gas escape while keeping air out of the vessel. We stock a standard bubbler airlock and a mini bubbler airlock for demijohns, each available in packs of 1 to 5.

The product details describe an S-shaped one-way valve made from food-grade plastic. Fit the airlock into a bored bung on top of your demijohn.
