Silicone Fermentation Airlock for Mason Jars

Availability: In stock (2)
Delivery time: 1-3 Days

Perfect for mason jar food fermentations. The one-way silicone airlock allows gas from fermentation activity to escape without letting oxygen in. No need to burp the jar or mess with water-filled cup airlocks. Fits most wide-mouth mason jars, and can be used with the standard metal locking ring for the lid.
