No one wants to drink from dirty beer lines! Improve the taste of your beer by eliminating foam-causing debris and beer stone, before they have a chance to build up. The rule of thumb is to clean your lines after every keg. With This attachment you can clean your draft system through the Sanke coupler. Just disconnect the keg from the coupler, and clean the entire line system with out disassembling the tap. That means less work and more frequent cleanings. This is just the attachment for your Sanke coupler and will adapt up to your existing draft line cleaning system through the shank attachment.
