This adapter fits both our pin lock and ball lock gas and liquid mfl disconnects and allows you to easily attach a liquid or gas line that is usually attached to a sanke coupler to a ball lock or pin lock keg.  Have a friend who usually buys sanke kegs from a brewery and want to bring them a keg of your delicious homebrewed beer?  This adapter will let you dispense from your keg without needing to alter their kegerator.
