PIPE COUPLING

PROBLEM TO BE SOLVED: To provide a pipe coupling for easily managing torque for a fastening nut, by preventing slipping-out of a pipe body under pressure, by eliminating an insertion shortage of the pipe body. SOLUTION: A coupling body 3 has a first through-hole 3c. Core metal 10 is fitted to and in...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pipe coupling for easily managing torque for a fastening nut, by preventing slipping-out of a pipe body under pressure, by eliminating an insertion shortage of the pipe body. SOLUTION: A coupling body 3 has a first through-hole 3c. Core metal 10 is fitted to and inserted into the tip part inner peripheral side of a hose 13, and the inner end side of the core metal 10 is arranged in the first through-hole 3c. A sleeve 11 is fitted to and inserted into the tip part outer peripheral side of the hose 13. The fastening nut 9 is connected to the pipe body connecting side end of the coupling body 3 while diametrally contracting the sleeve 11 by threadedly engaging with the outer peripheral side of the coupling body 3. The core metal 10 is formed separately from the coupling body 3, and a stopper step part 14 is formed on the inner peripheral side of the coupling body 3. The outer end of the core metal 10 is arranged in the same position as the outer end of the sleeve 11 when the inner end of the core metal 10 abuts on the stopper step part 14.
