Abstract: The present invention relates to a stabilizer (1, 26) which has at least two stabilizer components which are coupled with one another materially by thermal joining, characterized in that a heat-affected zone (7) produced by the thermal joining is at least partially heat treated after coupling. The present invention also relates to a method for producing a stabilizer (1, 26), wherein at least two stabilizer components are connected with one another by thermal joining, characterized in that the heat-affected zone (7) produced by the thermal joining is heat-treated.

Abstract: A connection assembly for attaching a pipeline to a distributor of a fuel or hydraulic system includes a threaded bushing placed adjacent to the distributor and having an internal bore in alignment with a connecting bore of the distributor, wherein the threaded bushing has a sealing seat. Disposed at one end of the pipeline is a sealing head which has a sealing surface and a pressure surface. The sealing surface and the pressure surface are each configured in the shape of a spherical segment defined by a radius of curvature having a center, wherein the center of the radius of curvature of the sealing surface is distanced from the center of the radius of curvature of the pressure surface. A union nut intended for connecting the pipeline to the threaded bushing forces the sealing surface of the sealing head in a pressure-tight manner against the sealing seat of the threaded bushing by at least indirectly acting upon the pressure surface.
