Threaded - Gas - Cornelius Keg Disconnect
Gas Ball Lock Disconnect
This MFL threaded gas in 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.
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.
