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 gas pushes out the top of the spout without letting air in.

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