Our one-way airlock fermentation lids are ideally suited to mason jars and are secured with a metal/stainless steel ring. This one-way airlock lid allows for carbon dioxide to escape while inhibiting oxygen from entering. This creates the ideal environment for fermentation, especially quick ferments such as veg mixes.

If you would like to order the airlock lid with a stainless steel band, view here.

The dimension of the one-way airlock fermentation lid is 82mm.
