White Wide Mouth Mason Jar Fermentation Lids with 3-Piece Airlocks – 2 Pack

This 2-pack fermentation lid set is made to fit standard 86mm wide-mouth mason jars and includes everything you need to get started fermenting right away. Each lid comes with a pre-installed silicone gasket and grommet, along with a 3-piece airlock. The setup takes less than a minute, turning your existing mason jars into reliable fermenters.

These lids are great for fermenting a wide range of foods and beverages—sauerkraut, kimchi, pickles, or even small batches of cider, beer, wine, and mead. The 3-piece airlocks allow gases to escape while blocking oxygen from entering, which helps create the proper anaerobic environment needed for fermentation.

The silicone gasket provides a secure, airtight seal to protect your ferment from outside air and contaminants. Each lid features a decorative design and is made from food-safe plastic that’s reusable and dishwasher safe. This set offers a practical, cost-effective way to repurpose mason jars for home fermentation projects.
