To remove a quick fitting, push down on the collet as you pull the tubing in the opposite direction. When you apply pressure to the collet, it prevents it from rising up to the top of the body where the taper activates the collet’s teeth. If you simply try and yank the tube out of the fitting, the teeth will engage and you will be unable to extract the fitting. By pressing down on the collet, you are keeping the teeth from compressing around the piece of tubing.

If you are struggling with a particularly stubborn quick-connect fitting, find an object you can use to leverage the pressure. For example, use the flat edge of a screwdriver to press the collect down as you pull the fitting toward you. If you are still unable to extract the tubing, use a collet release tool to press down the collet and remove the quick-connect fitting.
