These unique faucet plugs are designed to fit any faucet from 10 mm all the way up to 17 mm in diameter. These plugs are an economical solution to any fruit fly, yeast, or bacteria buildup when the faucet is not in use. The silicone is resistant to caustic and acid based cleaners as well as high temperature so they are dishwasher safe.

This cap also functions as the stopper for the malt extension tube on the Robobrew System. This cap will prevent grain from going down the tube.
