To start with, the ridge really helps make bung removal effortless. 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.

  • Also fits perfectly in a 2" tri-clamp ferrule

  • Stopper Measurements: 1.65" x 2.19" (42 mm x 55.5 mm)
