FIELD: construction.
SUBSTANCE: coupling is described for pipeline system for fluid medium, having seal with at least one sealing ring c in mainly D-shaped profile in section and with even radial external side, which adjoins even support surface in female part of coupling body. Thus in case of high torsional stiffness of according sealing ring, even if it is affected by comparably low radial pressing forces, quite a reliable seal is provided.
EFFECT: increased operational reliability.
