Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
1. This tool is used to create a double flared end on
Copper, Aluminum, Soft Steel and Brass tubing.
2. You may flare tubing from 3/16" to 1/2" in diameter.
3. Straighten tubing as much as possible, and then
be sure to make a clean cut straight across the
tube to avoid a crooked flare. Deburr inner and
outer edges. The tube cannot be crushed.
4. Back off the Flaring Cone and remove the
pivoting wing nut. Slide Yoke over Flaring Bar.
5. Loosen the two wing nuts and insert the prepared
tubing into the proper-size hole in the Flaring Bar.
The end of the tube must extend above the top
of the bar as much as the height of the Adapter
Shoulder. For the two smallest Adapters, extend the
tube as far as the shoulder on the largest adapter.

7. Lightly oil the appropriate sized Adapter and insert
it into the end of the tube, button end down.
8. Position the Flaring Cone over the Adapter.
9. Turn the Handle of the Yoke driving the
Adapter into the end of the tube. The tube
will flare. Continue flaring until the shoulder
