Airlock waterless fermentation lids for wide mouth mason jars

Silicone Fermentation Lids for Wide-Mouth Mason Jars – 8 Piece Set

Make home fermentation easier with these simple, reusable silicone fermentation lids. Designed to fit standard wide-mouth mason jars, they allow fermentation gases to escape automatically while helping protect your ferment from outside air.

One-Way Waterless Airlock

Each lid features a built-in one-way valve that automatically releases the gases naturally produced during fermentation. No water-filled airlock is required, making the system simple, compact, and easy to use.

The valve helps prevent pressure from building up inside the jar, so there is no need to regularly open the lid to release excess gas.

Food-Grade Silicone

Made from durable, BPA-free silicone, these fermentation lids are flexible, reusable, and designed for repeated use. The silicone construction creates a practical seal while remaining easy to install and remove.

Easy to Use

Simply place the fermentation lid on a standard wide-mouth mason jar and secure it with the jar's screw band. Once your ferment becomes active, the one-way valve allows excess gas to escape automatically.

A convenient raised finger grip at the top makes the lid easy to remove when your ferment is ready.

Easy to Clean & Reuse

The silicone lids are easy to wash and dishwasher safe. After fermentation, simply clean them along with your mason jars and they are ready for your next batch.
