Tools Required

J 29803-A Flaring Kit

1. Use the correct size steel pipe and fittings.

The outside diameter of the pipe specifies the size.




2. Cut the steel pipe to length. Add 3 mm (1/8 in.) to the length for each flare.
3. Install the fittings on the pipe before starting the flare.
4. Chamfer the inside and the outside diameter of the steel pipe with a deburring tool.
5. Remove all traces of the lubricant from the brake pipe and the flaring tool.
6. Clamp the flaring tool body in a vise.



7. Select the correct size collet and the forming mandrel for the pipe size that is being used.
8. Insert the proper forming mandrel into the tool body.
9. Hold the mandrel in place with your finger. Thread the forcing screw in until the forcing screw makes contact and begins to move the forming mandrel.



10. Slide the clamping nut over the brake pipe and into the correct collet. Leave about 19 mm (3/4 in) of the pipe extending out of the collet.
11. The brake pipe end must contact the face of the forming mandrel in order to insert the assembly into the tool body.
12. Tightly fasten the clamping nut into the tool body in order to prevent the pipe from pushing out.
13. Tighten the forcing screw with a wrench until the forcing screw bottoms. Do not over tighten the forcing screw. Over tightening the screw causes the flare to become oversized.
14. Take the clamping nut out of the tool body.
15. The flare is ready for use when the clamping nut and the collet (3) assembly are disassembled.
16. Use a pipe bender in order to bend the pipe.

Bending the pipe ensures a match to the old pipe.
