The Refco 525-F 45° Flaring Tool also burnishes your copper tubing to a clean, easy to use end (end surface must be oiled when flaring). This flaring tool allows you to flare the ends of your line yourself. The finished end is a 45° faceted cone. Its single-hole adjustable opening can be used for all sizes, including both metric (4.75 - 16mm) and inches (3/16" - 5/8").
Outer dimension metric sizes (mm) include 4.75, 6, 8, 10, 12,15 and 16. US sizes (inch) include 3/16", 1/4", 5/16", 3/8" , 1/2" and 5/8". It is applicable for all tubes.
Using the 525-F is easy. The yoke is removed to insert the tube into the adjustable opening in the tube-holding assembly. With about 1/8" coming through, tighten the clamp to secure the tube, and slip the yoke back over the tube-holding assembly. Twist to lock and flare.
The result is a perfect 45° flare.
