Pipe units connecting device for use in exhaust gas system, has sealing ring arranged in circulating recess, and clamping bracket surrounding conical extending sections of respective pipe units

摘要

The device has a pipe unit (10) with a conical extending section (10a). A pipe unit (12) has a conical extending section (12a) and a conical tapering section (12b). The sections (10a, 12b) partly over lap each other. A circulating recess, provided in the section (12b), is arranged in the overlapping area between the sections (10a,12b). A sealing ring is arranged in the recess, and a clamping bracket surrounds the sections (10a,12a). An independent claim is also included for an application of a pipe units connecting device in an exhaust gas system of an internal-combustion engine of a motor vehicle.
