The breaking force of the adjustment ring 32 and the size of the adjustment ring 30 can be adjusted by the width and the formation position of the flange 33. A lip 34 extending in the axial direction is formed in the adjustment ring 30, and a chamfer portion 36 having an inner diameter larger than the outer diameter d of the lip 34 is formed on the inner end of the nut end portion 25a. A screw projection 35 fitted to the male screw 23 of the joint body 22 is formed in the inner ring 35.

4. 발명의 중요한 용도4. Important uses of the invention

접속관을 통하여 유체가 흐르는 관 죠인트.Pipe joints through which fluid flows through connection tubes.
