Calibrator for tubes, specifically for the tubes extruded in thermoplastic material, in the act of leaving the extruder head, characterized in that it is constituted by a longitudinal frame applicable in the head of an extruder machine and that is contained within a vacuum chamber and that, in turn, accommodates in this longitudinal direction a coil spring, being arranged around this spring supports fixed thereto and other supports for peripheral support of the spring itself, so that a plastic tube protruding from the extruder runs at length of said quay, being applied on the inner face of the same to constantly maintain its initial diameter, until reaching the exit end, and so that not of the aforementioned supports is free to allow to adjust, by rotation at will, the internal diameter of the dock.
