This breathable silicone stopper fits 3, 5, 6 , and 6.5 gallon glass carboys and 500 ml flasks. This will not fill PET carboys or jugs.

A breathable Silicone stopper acts as both a stopper and an airlock. Its unique design allows CO2 to escape while keeping oxygen and airborne contamination out. It will also create a vacuum if the fermenting liquid cools (as opposed to pulling water in).

Great choice for fermenting wine, lagers, or anything with an extended fermentation time.
5 Stars
Loving these!
Using about 6 of these right now on gallon jugs of mead and they work great. No monitoring for liquid in an airlock or worrying about liquid being drawn into the jug from the airlock. Stoppers stay in well, much better than airlocks with rubber bungs.
