I use similar QDs (different model) on the gas side of my system. With those, I can swap out lines, remove lines from my kegerator and add on utility devices. You could also use these to easy swap between ball and pin lock lines.
Note that this is straight through/non-valved disconnect. This is a female disconnect. You need a compatible male disconnect to make a working connection.
