Airlock Lid for Gallon Jar
About This Item
Airlock lids create a one-way valve, allowing CO2 to escape and prevents oxygen from entering your jar. This reduces your chances of mold. For veggie fermentation, this pairs with our large ceramic pickle weights.
Lid diameter: 110 mm
Note: Airlock lids for gallon jars are not a universal fit for all gallon jars.
How To Use
Remove airlock cap, pour water to the "max" fill line. Put cap back on and insert into jar lid. This creates a one-way valve and reduces your chance of mold!
