<P>PROBLEM TO BE SOLVED: To provide a seal material removing tool which easily removes a seal material inserted in a spiral groove of a male screw or a female screw without damaging the spiral groove. <P>SOLUTION: The seal material removing tool removes a seal material deposited on a male screw of a coupling joint for coupling fluid conduits for leading the fluid to each other. A female screw engaged with the male screw is cut in the rotation-axial direction to thereby expose a cross section of a spiral groove of the female screw, and a cutting blade is formed at the cross section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
