Seal off your carboy with this breathable silicon bung! This bung is sized to fit standard carboys. It acts as both a solid stopper and an airlock, allowing CO2 to escape without allowing oxygen in. With a standard airlock, there is the possibility of pulling liquid in the airlock into the carboy when fermenting liquid cools. This airlock simply creates a better seal with no danger of sucking liquid in! Perfect for wine, lagers, or any other fermented beverage with an extended aging time./p>
