C017 HUGE #11.5 DRILLED STOPPER RED Solid Rubber Bung 2.30″ Top 1.89″ Bottom
Tapered rubber bung that will fit most Demijohns and some oak barrels. Top measurement 2.30″ and the bottom measurement is 1.89″ Metric is approx 58mmX48mm which would be about a #11.5 legacy size. Effectively seals carboy/barrel mouth for fermentation. Made of food safe material, the stopper has a 3/8″ drilled hole at the center of an otherwise solid rubber stopper for airlock or apparatus. This can be used to hold the air lock that allows a one-way gas exchange or another fermentation accessory. Works well with standard fermentation air-locks. A nice dark red, much darker than photo.
