Silicone Bung (Breathable) - Glass Carboy

Sale price$8.99


The silicone breathing bung can function as an airlock for extended aging of beer and wine. Made of natural white silicone, the bung has vent holes through the center, and a silicone flapper that fits tightly against the holes. This allows gasses to escape by pushing up against the flapper, and then the valve shuts protecting the product from contamination.

#7 breathing bung is recommended for use in glass carboys.
