とを特徴とする管継手。By fitting the tube to be connected into the insert of the joint body and screwing the tightening nut into the joint body,
A sleeve is press-fitted between the fitting body and the outer surface of the tube into which the insert is inserted, so that the tubes are connected in a sealed state, and the above-mentioned fitting bodies are inserted and fixed into separate bodies. The body is formed by an insert, and the body is formed with a first enlarged diameter part and a second enlarged diameter part whose diameter increases sequentially on the tube insertion port side of the fluid flow path, and the insert is formed by pressing a thin metal plate into the first diameter part and the second enlarged diameter part.
The tube is configured to include a large diameter portion having a shorter axial length than the first enlarged diameter portion that is inserted into the enlarged diameter portion, and a small diameter portion into which the tube is externally fitted, and is inserted into the first enlarged diameter portion of the body. The protruding wall of the body formed by caulking the step between the first enlarged diameter part and the second enlarged diameter part with the large diameter part of the sleeve inserted is inserted between the large diameter part and the small diameter part of the sleeve. A pipe joint characterized by engaging a shoulder between the pipe joints.
