FIELD: machine building.
SUBSTANCE: in sealing coupling for piping containing internal pipes for electric conductors, such as cables, and flexible shell enclosing the internal pipes, containing the piping enclosing coupling cups, in particular coupling half-cups that limit input hole and output hole for pipes, sealing mat divided in longitudinal direction of the seal coupling, sealing washer to seal output hole for pipes with passages, each of which is intended to locate internal pipe with making of the circle closed sealing surface for the internal pipe, and intended for external installation on the coupling cups of the clamping device to press to each other the coupling cups, and for radial pressing of the sealing mat to shell of the piping, it is provided that sealing mat has several circle, passing radially inside to shell of ring bulges to seal the input hole, and between two ring bilges creates circle ring groove, in which during compression the appropriate elastically deformed ring bilges can enter such, that circle closed seal surface is created for the shell between the ring bilge and shell.
EFFECT: sufficient sealing function both in input hole and output hole for pipes.
