Claims

[Scope of utility model registration request]

A cylindrical joint body 11, a nut member 12 that is screwed into the nut member 12, and a thick wall portion 13a that is disposed inside the nut member 12 and has a tapered surface 13d on the inner edge of the tip that matches the conical end surface 11c of the joint body 11. The cylindrical metal 13 is formed of an intermediate thin portion 13b and a locking portion 13c having a tapered surface 13e on the outer periphery that matches the conical cam surface 12b at the rear end of the nut member and an annular pawl 13f on the inside. 13f to conduit 14
In a flareless pipe joint in which the conduit 14 is connected by being depressed, the conduit 14 is connected to the inside of the tube metal 13.
It is made of a harder material and is formed of a flange 15a at the tip and a cylindrical portion 15b having an outer diameter slightly smaller than the inner diameter of the conduit 14, and when the flange 15a is brought into contact with the rear end surface of the joint body 11, the rear end becomes an annular claw. A flareless pipe joint in which a sleeve 15 with a length protruding from 13f is disposed, and a cylindrical portion 15b of the sleeve is fitted into a conduit 14 to connect the conduits.
