摘要： A manually operable hand tool apparatus for providing a radially outward flare, known as push connect flare, away from the distal end of a deformable tube. The hand tool comprises a gripper-die means for securing the tube, a yoke portion having internal threads and a manual hydraulic pump portion. The yoke moves axially on a threaded positioning screw that is rigidly connected to the manual hydraulic pump portion. A vise means comprising a screw and a tightening rod is attached to the yoke. The vise is used to secure the gripper-die means to the yoke. The pump portion comprises a cylindrical body, a flaring piston, a threaded positioning screw, a pumping linkage system and a relief valve. An adapter-die is secured by a guide nut which is connected to the flaring piston. Alternative adapter-die and guide nut designs are also used to connect the die to the flaring piston. A lever arm is used to pump oil and to energize the flaring piston, thereby forcing the adapter-die to deform the rigidly restrained tube into the outward radial flair.
