Plastic Series Cleaning Cup for Guinness (U System), Micro Matic

A beer system series cleaning cup is sometimes called a keg coupler flusher. A keg coupler flusher, like this specific unit, is used to make an easy coupler connection for cleaning purposes. If you have two beer lines running from the same draft beer system and are trying to figure out how to clean beer lines most efficiently, this product is right for you. By connecting two U System couplers with flusher fittings and adapters, you can clean two beer lines at once and do the same work in half the time.
