Turn wide-mouth Mason jars into convenient fermentation vessels with five silicone airlock lids designed to vent gas automatically while you make kimchi, pickles, sauerkraut, salsa, or other fermented foods.
-
Automatic venting: The waterless airlock releases fermentation gas without requiring you to burp the jar or maintain water levels.
-
Wide-mouth fit: Each 3.3-inch diameter lid is designed to fit wide-mouth Mason jars, giving you a simple sealing option for home fermentation.
-
Food-contact silicone: You get flexible, food-grade silicone lids that are BPA-free, mold-free, and odorless.
-
Easy cleaning: Wash the lids by hand or place them in the dishwasher, then reuse them for future batches of probiotic fermented vegetables, fruits, and more.
