Double Inverted Flaring

DOUBLE INVERTED FLARING

A pre-formed metal tube is recommended and preferred for all repairs. However, double-wall steel tube can be used for emergency repair when factory replacement parts are not readily available.

Special bending tools are needed to avoid kinking or twisting of metal brake tubes. Special flaring tools are needed to make double inverted flares or ISO flares.





1. Cut off damaged tube with a Tubing Cutter.
2. Ream the cut edges of the tubing to ensure a proper flare.
3. Install the replacement tube nut on the tube.
4. Insert the tube in the flaring tool.
5. Place the gauge form over the end of the tube.
6. Push the flaring tool through the flaring tool jaws until the tube contacts the recessed notch in the gauge that matches the tube diameter.
7. Tighten the tool bar on the tool.
8. Insert the plug on the gauge in the tube. Then swing the compression disc over the gauge and center the tapered flaring screw in the recess of the compression disc.
9. Tighten the tool handle until the plug gauge is squarely seated on the jaws of the flaring tool. This will start the inverted flare.
10. Remove the plug gauge and complete the inverted flare.
