ジが該設された金属製の外筒部と合成樹脂層にて
形成される内筒部とからなり、外筒部と内筒部と
の間に接続管の端部が挿入される挿入部が形成さ
れてなる管継手において、前記内筒部の外面に前
記接続管の端部に弾接し得る弾性パツキングと水
膨張性シール材とが装着され、該水膨張性シール
材が該弾性パツキングより接続管側に配置されて
いることを特徴とする管継手。 The connecting part to which the end of the connecting pipe is connected consists of a metal outer cylinder part with a female thread on the inner surface and an inner cylinder part made of a synthetic resin layer, the outer cylinder part and the inner cylinder part. In the pipe joint, an insertion part is formed between which an end of a connecting pipe is inserted, and an elastic packing capable of coming into elastic contact with the end of the connecting pipe and a water-expandable sealing material are provided on the outer surface of the inner cylindrical part. A pipe joint, wherein the water-expandable sealing material is disposed closer to the connecting pipe than the elastic packing.
