Abstract: A metallic fluid tube includes a metallic tube wall having a tube wall inner side which delimits an interior space and a tube wall outer side facing away from the interior space and toward an exterior area. The tube wall has a tube end with a tube opening connecting the interior space with the exterior area. The tube wall has an elevation which runs around the tube wall outer side and is arranged spaced apart from the tube end. The tube wall outer side has a circumferential sealing geometry extending on the tube wall outer side from the elevation to the tube end. The circumferential sealing geometry has turning grooves extending along a groove extension direction that runs transversely to a longitudinal extension direction of the fluid tube.

Abstract: The present disclosure relates to a fluid connection arrangement for establishing a fluid connection, including a receiving part having a receiving wall that has a receiving wall inner side that delimits an interior of the receiving part, a tubular connecting part that is at least partially received in the interior of the receiving part and has a tube wall having a plurality of comb-shaped support points that extend along a longitudinal direction of the tubular connecting part, the comb-shaped support points contacting the receiving wall inner side. The tube wall may have at least one curved wall area that extends between two adjacent comb-shaped support points. Between the at least one curved wall area of the tubular connecting part and the receiving wall inner side of the receiving part at least one gap is arranged where a solder is received to establish a materially bonded and fluid-tight connection.

Abstract: The present invention relates to an arrangement with a tubular element, preferably a pipe or a hose, and a coupling device, which exhibits a tubular section, the internal diameter of which is larger than the external diameter of the tubular element and in which the tubular element is in some sections arranged in the tubular section. To improve this type of arrangement, provision is made according to the present invention in that a pre-fabricated, preferably annular adhesive element of essentially fusible adhesive is arranged between the tubular element and the tubular section.

Abstract: The present invention relates to a fuel cooler comprising at least one cooling module having a flow channel formed therein, the cooling module comprising at least one joining means for joining with at least one further cooling module.

Abstract: The present invention relates to a coupling, in particular a quick coupling, for connecting lines, said coupling comprising a first connection area and at least one second connection area, said first connection area being provided, at least sectionwise, with a section which is adapted to the contour thereof. Said section comprises energetically activatable particles and is adapted to be brought into contact with a line end of one of the lines to be connected.
