とを特徴とする管継手。A sealing material pressure contacting surface and a back end stepped surface on the inner side of the sealing material pressure contacting surface are formed on the inner surface of the socket, and an annular sealing material is arranged between the sealing material pressing surface and the outer surface of the insertion port. An annular press ring having an inner peripheral surface smaller in diameter than the outer surface of the insertion hole is provided on the back side of the sealing material, and by screwing out from this press ring and pushing the step surface at the rear end, the press ring conversely closes the seal. In a pipe joint provided with an appropriate number of press bolts in the circumferential direction for compressing the material, the annular recess between the push ring and the inner step surface has an inner circumferential surface corresponding to the inner diameter of the pipe line, and an appropriate number of push bolts in the circumferential direction. A ring body divided into several parts is inserted, and a filler is filled in the gap between this ring body and the press ring, the gap between this ring body and the back end stepped surface, and the gap between the ring bodies in the divided part.
