Review on OTC 4504 Stinger Bubble Flaring by Hunter Schneider

What can I say. It worked. I did 14 lifts with only one issue from not tightening the wing nut enough to keep the line from slipping. When I did everything there was not a single leak. I made 7 replacement lines at the factory and routed them exactly as they came from the factory. I used 3/16" polymer coated cord (dark green material). OD Deburrer I used a chamfer tool to make a chamfer on the ID, then I oiled the included die and proceeded to create the torch. Bench grinder, just this one Once I used a fibrous buffing pad to remove all of the polymer coating from the surface of the expandable area I didn't go to the buffing wheel just to remove the green streaks The only reason I didn't give it 5 stars is is that it doesn't work as well as a $350 tool.have it.would buy it again i think.
