ABSTRACT:
A nut adapter to be formed to hardly twist a pipe welded to a cap nut clamping fluid joint or eliminate the twist of the pipe when clamping the cap nut of the fluid joint, and a fluid joint having the nut. This nut holds a thrust bearing at a position of the nut, corresponding to the surface of the nut for pressing a sleeve when clamping the nut so that, when an unreasonable force is applied, the nut and the sleeve rotate together so as not to transmit a rotary torque to the pipe.
