The present device relates to an easily distinguishable industrial air tube on which a standard-displaying part is formed on a surface of each air tube to easily distinguish the standard of the air tube, to thereby improve convenience in use. For this purpose, an air tube for pneumatic, painting, and piping applications used in various industrial settings includes a standard-displaying part (20) having a plurality of display lines (21) for displaying the standards for the outer diameter, thickness, and material of the air tube (10) such that the standards of each air tube (10) are displayed on an outer surface of the air tube (10) in order to easily distinguish each air tube. |
