The set includes 3 inline quick disconnects sets, hose clamps, and extra tubing. The inline quick disconnects seal on both ends when the set is disconnected so you can disconnect them and not loose all your gas.
Set up: Turn off your gas tank and disconnect the tap from the keg. Cut the lines approximately 4-6 inches away from the tap and put a set in each line. **Tip: if you switch the order of the qd sets on the lines it will make putting new taps on extremely easy, even someone who has never used a tap can't accidentally hook your beer out fitting into your gas line. The 3rd set of quick disconnects are to be hooked up to the supplied extra tubing to go on the Cornelius style keg qd's. Please note the orientation of the qd's on the beer and gas line so you put the fitting on the appropriate side.
Use: The inline qd's are opened by pushing down on the stainless lever, then pull the qd's apart. They do seal when separated, however some dripping may occur on the beer side. To engage, simply slide the male side into the female till you hear a click or it won't separate when you pull them apart. You may have to push in on the stainless lever to get the male to go in.
