Airlock + Fermentation Lid - Combo

Complete Your Fermentation Setup: Weck Lid & Airlock Combo

Eliminate the guesswork from your probiotic projects. The Weck Fermentation Lid and Airlock Combo is the gold standard for home fermenters who want a reliable, airtight seal during the active bubbling phase.

By combining the custom-fit Weck plastic lid with our fermentation airlock, you create a one-way valve system. Carbon dioxide produced by your "good bacteria" can safely vent out, but harmful oxygen and wild yeasts are blocked from entering. This significantly reduces the risk of surface mold and ensures a crisp, tangy result every time.

Key Features

• Ready-to-Use Set: Includes one BPA-free Weck fermentation lid with a pre-fitted grommet and one classic 3-piece airlock.

• Contamination Shield: The airlock acting as a barrier is the best defense against "kahm yeast" and spoilage.

• Universal Weck Fit: Specifically molded to snap onto Weck glass jars, providing a tighter seal than DIY solutions.

• Visual Monitoring: The clear airlock allows you to see the "bubbles" in action, so you know exactly when your fermentation is most active.

• Durable & Reusable: Designed for repeated use across hundreds of batches.

Note: Not dishwasher safe. Temperature-resistant from -30° to 70° Celsius.
