I currently keep my co2 tank (20#) outside the kegarator. I use 1/4" braided line and I want to use a quick disconnect of some kind. I have one of those "carbonator" thingies that goes on a 2-liter bottle & carbs up anything in it. I don't want to have to go inside the kegarator every time and have the door open while I carb. I also want to get a beer gun sometime in the near future, and same issue goes. Anyway, what's the best way to set that up?
Edit: This kind of line:
