This set comes with a black, beverage-out quick disconnect and a white, gas-in disconnect. Both are barbed for attaching to a beverage/gas line, and its high quality construction creates a sturdy seal that won’t leak gas or beer when in use.
The barb measures 1/4 inch, so 3/16 inch beverage tubing is recommend for the perfect fit.
Note: Sometimes ball lock fittings can be difficult to get fully seated on a Cornelius keg. We recommend using a quick spray of sanitizer solution to act as a lubricant and giving it a few twists while applying the ball lock.
