Unique, self-adjusting, tube holding mechanism permits flaring any size tubing within the range of 3/16″ to 5/8″ (4.75mm to 16mm) O.D. Innovative, the single-opening design is more compact and easier to use than conventional multi-opening flaring bars. Faceted, hardened steel, chrome finished cone rolls out and burnishes perfect 45° flare above the tube-holding mechanism reducing the need for deburring. Original wall thickness is maintained of the base of flare. Slip-on-self-centring yoke permits use in tight quarters. Large handle with better leverage and precision threads on feed screw make flaring effortless. High-quality construction with satin chrome and black finish
