These packs of 4 silicone fermentation airlock lids and stainless steel bands are perfect for keeping lacto-fermented pickles and drinks under an airlock during fermentation and storage. As pressure builds up, the gas pushes out the top of the spout without letting air in.

Each lid has a stainless steel screw band that fits wide-mouth glass preserving jars. These large 2-liter jars are great for use with these airlocks for making sauerkraut or brewing water kefir.  They also fit these 1-liter glass jars for smaller batch fermenting.

Perfect for Making Kefir, Kimchi, Sauerkraut, and other lactic vegetable ferments. Use together with our glass fermentation weights, or buy our Easy Fermentation Starter Kit.

Made from FDA-approved, food-grade silicone and stainless steel, the lids can be washed in the dishwasher and reused.
