PROBLEM TO BE SOLVED: To provide a tool for displaying all numerics corresponding to one nominal diameter of the specification table of a tube by a simple operation. SOLUTION: This tool is configured of a display board 1 and an exterior body 2 housed so as to be slidable to this. The specification table of a tube for piping is fixed to a first surface 11 of the display board 1. The specification table of a flange is fixed to the second surface of the display board 1. The exterior body 2 is provided with a first board covering the first surface 11 of the display board 1 and the second board covering the second surface of the display board 1. The first and second boards of the exterior body 2 are configured so that printing is applied in black on a white ground, and paper equipped with a plurality of window parts is bonded to each transparent board. The exterior body 2 is made to slide to the display board 1 so that all numerics corresponding to one nominal diameter of the specification table of the tube can be simultaneously displayed in each window part of the first board of the exterior body 2, and that all numerics corresponding to one nominal diameter of the specification table of the flange can be simultaneously displayed at each window part of the second board of the exterior body 2.
