Threaded - Liquid - Cornelius Keg Disconnect
Liquid Ball Lock Disconnect
This MFL threaded liquid out disconnect for Cornelius kegs has a ball lock connection.
If you go with a threaded fitting, you can get a better fit onto the 5/16" tubing which is a universal tubing size.
Threaded disconnects are also useful for switching beer and gas serving lines around to counter-pressure bottle fillers.
As you can see, the threaded connectors allow for all sorts of extra functions and possibilities.
Please see products below for the threaded Nut & Tail - providing the option for a barbed end.
