No beer line cleaning kit is complete without a fully functioning cleaning bottle cap. This pressure relief valve helps regulate the pressure being pushed through your draft system and fits D System, S System, U System, G System, A System, and M System pressurized cleaning bottle caps.

These caps work 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.

Ensure safety from overpressurization of your draft beer system by replacing this part if it is damaged or lost.
