Luer Locks disconnects are generally used in medical and industrial applications.  Compatible male and female Luer Locks twist together to make a airtight, pressure capable connection.

I use Luer Lock style connectors for a CO2 utility line for my draft system.  That allows me to quickly and easily switch between a number of CO2 utility attachments that I don’t use on a day to day basis.  The reason I chose Luer Locks is that they are generally inexpensive.  You could also use these as a primary disconnect for your CO2 system.
