If you refill your 5-gallon water bottles, at some point the sticker covering the hole in the cap will fall off. What to do? These plugs fit snugly into the hole in a Primo 5-gallon water bottle cap. The goal was for them to be splash-resistant, hence the scallops and ribs. This worked better than planned as testing showed them to be water-tight!
