Abstract
The invention concerns a conduit element made of metal for uncoupling high frequency vibrations in connection with exhaust gas conduits of motor vehicle internal combustion engines. To improve the uncoupling of these high frequency vibrations, the conduit element of the invention basically comprises a screw thread-shaped or annularly undulating short corrugated sheathing hose of high rigidity inserted into the exhaust gas conduit, as well as a knitted jacket placed on the waved corrugated sheathing hose segment in a force-locking or form-locking manner.
