Premium breathable silicone barrel bung. The built in tabs really help make bung removal effortless. Two-piece design. When 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 "breathe" out, you just push the center cap into the bung to create a firm seal and it becomes a solid stopper!

Fits most 30 and 60 gallon barrels as well as the hole in the lid of most Variable Volume tanks!

Tapers from 1 7/8" to 2 1/4" diameter
