Silicone Bung for Small Barrel - Breathable
FE489
High quality breathable silicone bung, designed to fit a small barrel. When the two-piece is set to the open position, the bung acts as an airlock and allows the release of CO2 while maintaining a seal against oxygen coming in. This makes the bung ideal for alcoholic or malolactic fermentation in barrels or tanks. When fermentation is over and you no longer want the bung to "breath" out, you just push the center cap into the bung to create a firm seal and the FE489 becomes a solid stopper!
Dimensions are 1 7/8" tapering down to 1 1/2". Fits some small barrels, including the 6.1gal Vadai, and the Better Bottle plastic carboy.
