Abstract: A fluid coupling includes a housing having a seal mounted in a bore. An endform has a tip portion extending from a tip end and a retainer engagement surface which is engaged by a retainer movable in the housing to latch the endform to the housing. A protective layer is disposed on an exterior surface of the endform extending from an end spaced from the tip end of the endform and defining a bare exterior surface on the tip portion of the endform which is directly engaged by the seal.

Abstract: A fluid quick connector couples an endform having a raised flange in a bore of a fluid operative element. In one aspect, a retainer in the form of a plate has opposed edges forming channels movably mounting the plate on a housing. Side tabs releasably lock the retainer in a moved position to latch the endform in the housing. In another aspect, the retainer includes spring arms which bias the retainer to the second position. The retainer is held in the first position by a lip of a top hat extending outward from the housing. The top hat moves longitudinally inward upon engagement with an endform to free the spring arms to automatically move the retainer to the second position latching the endform in the housing.

Abstract: A multiple walled tube is rolled from a metal strip for transporting fluids, specifically in automobile engineering, where the metal strip consists of stainless steel. A method for manufacturing such a tube, where the stainless steel strip is brazed in an H2 atmosphere after rolling, specifically by the addition of a brazing solder.
