Review on ABN Automotive Conditioner Quick Disconnect by Zane Myers

They are required when you are replacing or repairing the A/C line on your car TRUCK. Connectors require some kind of tool like this. The youtube videos don't really show the shutdown part. Probably too much bird talk. There are different styles and prices but they were suitable for the use I needed. If I work with air conditioners a lot, maybe I would choose something else, maybe not. Removing the freon cord is a little tricky even with them so be patient, make sure the retaining spring is pushed all the way back, you can't see it so press down on the release tool with all your strength and pull on the cord to remove to separate them The joint. You will eventually get the hang of it, but it will take some trial and error.
