Abstract: The present disclosure relates to a hose line for a fluid comprising a support layer, a first barrier layer configured to prevent the diffusion of the fluid, and a second barrier layer, wherein the first barrier layer is arranged on the internal side of the hose line and the second barrier layer is arranged between the first barrier layer and the support layer. The present disclosure further relates to a method for producing a hose line.

Abstract: In order to effect an impervious and, at the same time, stable connection of fluid-conducting ducts, especially of hoses or pipes, a coupling having a connector is provided in accordance with the invention, which cooperates with a duct at least portion-wise, with the connector comprising at least one adhesive space which is filled with an adhesive. According to the method of connecting ducts a coupling according to the invention is used, whereby the connector of the coupling is, for instance, mounted on a duct and a thermal treatment is carried out, during which both the adhesive is hardened and the duct is thermally deformed.

Abstract: The present invention relates to a line, in particular for fuel tank filler systems, which comprises a blocking layer 1 and a cover layer 3. For improving especially the mechanical properties, the blocking layer 1 and the cover layer 3 have provided between them an intermediate layer 2 which is made of nitrile butadiene rubber and which has admixed thereto an adhesion promoter made of a phosphonium compound.

Abstract: The present invention relates to a press tool for connecting a tubular element to an element which is arranged in the interior and substantially adapted to the inner diameter, the press tool comprising at least one press jaw and a pressure distributing element which is annularly arranged between the press jaw and the outer circumference of the tubular element and which exhibits the characteristics of an incompressible liquid and which is arranged around the connecting portion of the elements to be connected and distributes the pressing power generated by the press jaws substantially over the outer circumference of the tubular element. Furthermore, the present invention relates to a method for connecting a tubular element to an element which is arranged in the interior and substantially adapted to the inner diameter, wherein pressure which is evenly distributed over the circumference of the tubular element is exerted at the same time to the exclusion of leaky spots.
