This $585 thin wall tubing tool you show a link is for copper and aluminum only according to the information. You cannot safely use either metal for tubing brake lines on an automobile. Try to double flare with SS and you will split it around the circumference of the bend fold. Why would you even want to consider double flares in AN fittings that are designed for and only require a single flare?
