(54) Reflare tool and process


(57) A flaring body (220) has first (235) and second (240) opposing ends. A perimeter surface (242) intersects the first end, and a flaring surface (245) is located between the perimeter surface and the second end. The perimeter surface has a first cross-sectional profile (250) with a first area, and the flaring surface having a second cross-sectional profile (255) with a second area less than the first area. The perimeter surface and the flaring surface are joined by an inside, rounded corner (246). A crimping body (230) has a top surface (232) and an opposing bottom surface (285), and an interior surface (260) that defines a passageway (270) that connects said top and bottom surfaces (232,285). The interior surface has a third cross-sectional profile with a third area larger than the first area. The flaring body (220) is slidably captureable in the passageway (270). The interior surface further has a crimping channel (280) that extends along at least a portion thereof and terminates at the bottom surface (285).
