Pickle Pipe airlocks are the easiest way to vent fermentation gas. The one-way valve automatically releases gas, without letting in any oxygen that can cause spoilage, so jars don't have to be babysat and manually burped daily. Fits any regular mouth mason jar. Mad of food safe, BPA-free silicone. Dishwasher safe.
We recommend using this product with fermentation weights, like Pickle Pebbles.
