摘要 A tubular joint including a conical male thread and a conical female thread. An annular housing is disposed close to a free end of the female element and is used to house a deformable sealing ring. The sealing ring is in sealed contact with the peripheral surface of the housing and with diminishing threads of the male thread and bears axially against a shoulder that faces the free end, thereby limiting the housing.
