Connecting arrangement for coolant lines

摘要

A connecting arrangement for coolant lines includes a first coupling piece, connected seal-tight to a first line endpiece, and a second coupling piece, connected seal-tight to a second line endpiece. The coupling pieces each have radially extending sealing surfaces on the side facing toward the other coupling piece. A sealing ring is mounted between the sealing surfaces. The coupling pieces are joined to each other via a screw arranged laterally offset from the sealing surfaces so the line endpieces connect to each other via respective bores in the coupling pieces. A form body between the coupling pieces arranged at a spacing from the screw on the side facing away from the sealing surfaces is configured so a lever action occurs when the coupling pieces are joined to each other leading to a uniform pressing together of the sealing ring between the sealing surfaces of the coupling pieces.
