5.0 / 5.04 ReviewsGreat!Works great with 1 gallon glass jungs for an airlock.December 30, 2012WorksFits and works as advertised. Also very cheap.December 24, 2012works as expectedit fits and the price is rightJanuary 4, 2013It is, what it saysWorks for it's intended purpose. Fits great, but I would recommend putting air lock in stopper before putting stopper in jug. The inside diameter of the jugs can vary and you don't want to push the stopper into the jug.July 6, 2017Purchased
