If you’re using a U System coupler, you can use this cap with either our 15-Liter or 5-Liter pressurized beer line cleaning kits to make your life easy. Just untap your keg, fill the cleaning bottle with solution, attach the pressurized cleaning bottle to your keg coupler, and place a bucket under the tap faucet. The cleaning solution will run through the beer lines the way your beer would.

Beer line cleaning has never been a simpler task. This part will ensure that the cleaning bottle is attached to your S system keg coupler.

This U System cap fits stouts such as Guinness, Harp, & Bodington. Not sure which keg coupler your draft beer system is using? Consult our Keg Coupler List.

Please note, this cap is strictly for draft beer line cleaning.
