One-way airlock fermentation lid for glass jar [WITH STAINLESS STEEL BAND]

Ideally suited to mason jars and is secured on 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 a veg mixes.

This listing includes the stainless steel band and stainless steel seal which will not rust. We also have a listing for airlock lids without stainless steel bands and seals.
