Claims

[Scope of utility model registration request]

A joint body 1 is provided with a connecting cylinder part 1b for inserting a tube, which has a threaded part 10 for screwing a cap nut on the outer peripheral surface, on the front end side of a cylindrical main body part 1a, and the joint body 1 is connected to the joint body 1. The O-ring 5 and the chuck sleeve 3 are fitted onto the outer periphery of the connecting end of the tube a to be inserted into the inner cavity of the cylindrical portion 1b, and the chuck sleeve 3 is screwed into the threaded portion 10 of the connecting cylindrical portion 1b of the joint body 1. In a joint for connecting a tube, the joint body 1 includes a cap nut 4 that presses and compresses the chuck portion 3a of the chuck sleeve 3.
an inner cylinder b that fits into the inner periphery of the connecting end of the tube a inserted into the connecting cylinder part 1b, on the front end side of the
A joint for connecting a tube, characterized in that it is installed so as to protrude toward the inner cavity of the connecting cylinder portion 1b at least to the tightening position of the O-ring 5.
