ATD Tools 5483 Professional Master In-Line Flaring Tool Kit for Automotive Brake Lines - Perfect for DIY Car Repairs & Professional Mechanics

This is a pretty good set and worth the money. It's much better than the traditional bar type flare tool and this will work in tight spaces. I actually ruined a die. Long story but it was completely my fault, but the dies are made of soft steel (the dies in all sets look that way I don't think it's a problem with ATDs set). The good news is I was able to find a replacement ATD die online so being able to find parts easily is a plus for me.Here is my method for flaring that I decided to use after practicing with the tool some, but follow ATDs directions, practice, and find your own method.For Double Flare1. Cut tubing. Hold tubing upside down and deburr and chamfer the end (this helps shavings fall out of tubing).2. Insert tubing in the die. Alternate tightening of die screws. Use the flaring adapter as a spacer for how far tubing extends from die (Diagram 1)3. Back hex yoke screw far out of hex yoke so it will thread on the die (If the hex yoke doesn’t thread on by hand something is wrong don’t force it with a wrench). Lubricate both sides of the flaring adapter with silicon grease. Place flaring adapter stem into tubing. Hand tighten (do not use a wrench) hex yoke onto die (Diagram 2).4. Grip hex yoke with 7/8” wrench and turn hex yoke screw with 9/16” socket or wrench. Do not over tighten. Grip ratchet near its head so you can’t use too much torque. Just tighten until firm (Diagram 3).5. Take off hex yoke and examine the bell shape formed in tubing.6. Remove flaring adapter. Lubricate point of hex yoke screw with silicon grease and reinstall hex yoke.7. Tighten hex yoke screw firmly again. Then back screw off and inspect flare*Tightening Tip: As the hex yoke screw is tightening you will need to apply a constant amount of torque as the flare is being formed. Turn the screw slowly and pay attention to the torque you are using. When you feel the torque needed to turn the screw suddenly increase you know that your flare is finished.
