Mason Tops 4-Pack Pickle Pipe Wide-Mouth Mason Jar Silicone Fermentation Airlocks

The Pickle Pipe is the world's first one-piece， self-sealing， silicone and waterless airlock. When fermenting your own vegetables， it is important that carbon dioxide is allowed to escape (or else the jar can explode) and that oxygen is not allowed to enter (or else your food will spoil with mold). The Pickle Pipe maintains the perfect， maintenance-free fermenting environment without the need to burp your jars every day， or monitor the water levels of a clumsy 3-piece airlock. The patented Pickle Pipe will allow you to "set and forget" your ferments without the daily maintenance of every other airlock solution in existence. The low profile design allows you to store your ferments in tight spaces， and when finished， simply pop them in the dishwasher for years of use. There is no easier or more convenient solution to worry-free mason jar ferments.
