The Maddox Flaring Tool Kit is designed for creating double and bubble flares on copper, aluminum, soft steel, and brass tubing. Before use, ensure you are wearing ANSI-approved safety goggles and heavy-duty work gloves. Always inspect the tool for damage or binding parts before starting. The quality of the flare depends on the preparation of the tubing; ensure it is cut cleanly, deburred, and straightened.

Double Flaring Instructions
- Straighten the tubing and make a clean, straight cut. Deburr the inner and outer edges.
- Insert the tubing into the correct sized hole on the Flaring Bar.
- Place the same-sized Flaring Adapter on the surface of the Flaring Bar, flat side down.
- Adjust the tubing height so the end aligns with the step on the Flaring Adapter.
- Hand-tighten the wing nuts, starting with the one closest to the tubing, until it cannot slip.
- Insert the stem of the Flaring Adapter into the tubing end.
- Position the Flaring Yoke over the Flaring Bar so the cone enters the depression in the adapter.
- Turn the handle to force the cone down until the adapter rests flat against the bar.
- Back off the yoke and remove the adapter.
- Reposition the Flaring Cone over the tubing and screw the yoke down until the tubing folds back on itself, forming a 45-degree double flare.
- Loosen the yoke and wing nuts to remove the tool.
Bubble Flaring Instructions
- Straighten and deburr the tubing.
- Insert the tubing into the correct sized hole on the Flaring Bar until it is flush with the top.
- Hand-tighten the wing nuts until the tubing cannot slip.
- Remove the cone from the Yoke and thread the correct-sized bubble flaring adapter onto the Yoke screw.
- Position the Yoke over the Flaring Bar so the adapter stem enters the tubing.
- Turn the handle to force the adapter down until it rests flat against the clamping assembly.
- Back off the Yoke and remove the adapter.
- Loosen the Yoke and wing nuts to remove the tool.
