PURPOSE: A nut assembly device for thermoplastic plastic tube is provided to improve a distortion of the thermoplastic plastic tube by constantly maintaining inserting force of an inner in an assembly of the nut into the plastic tube. CONSTITUTION: A nut and a sleeve are inserted into an outer circumference of a thermoplastic plastic tube, and an inner is assembled to an inner portion of the plastic tube. A nut assembly device for thermoplastic plastic tube comprises a bracket(10), a loading die(20), a stopper(30), an actuator(40) fixed to the bracket, and a pin(50) inserted into the actuator at its one end and is operatively connected with the actuator at its the other end. The pin is linearly moved toward the plastic tube seated in the stopper so as to insert the inner into the inner portion of the plastic tube.
