Claims

[Claims for Utility Model Registration] 1. A tube joint that prevents the tube from coming off by forming a deformed portion on the tube when the tube is attached, which has a male threaded portion 1, an annular groove 2 on the circumferential surface, and a tapered surface on the end. 3 is fitted into the groove 2 of the tube fitting part 4 so that the circumferential surface of a tube T made of fluororesin or the like is inserted into the groove 2 of the tube fitting part 4. A ring 6 with a split groove, a female thread 7 screwed into the male thread 1, and an inclined inner wall 8a that abuts the ring 6 and applies compressive force to the tube T from its outer surface toward the center. A tube T is provided on the upright inner wall 8b and the tapered surface 3.
A tube joint comprising a cap nut 11 having a tube outlet hole 10 connected to an inclined inner surface 9 which presses the two. 2. A stepped portion 12 between the male threaded portion 1 and the tube attachment portion 4 that brings one side of the ring 6 into contact, and a large diameter portion 14 that has a groove 13 in which the end of the tube T is inserted into the stepped portion 12. The tube diameter according to claim 1, further comprising:.
