A clamping element axially movable in the receiving opening cooperates with an inner surface of the housing body to secure the line end onto the inner sleeve. Media-tight outward sealing is accomplished by sealing engagement of the essentially rigidly secured inner sleeve in the line, because the inner sleeve itself is also tightly joined to the housing body.

Abstract: A process for forming a radially upset tube flange particularly suitable for securing a connector on an end of a tube, and a connector assembly formed thereby. A connector is provided, having an end face and an away face. A desired length of tube is provided, having an end portion and a tube end. The connector is passed over the end portion of the tube, with the end face of the connector nearest the tube end and the away face of the connector farthest from the tube end. The tube is gripped with a fixture, and positioned with the away face of the connector against the fixture. A preferred length of the tube end portion extends axially beyond the end face of the connector. Force is applied axially to the tube end, causing a major radially outward upset of the tube against the end face of the connector and a minor radially outward upset of the tube against the away face of the connector. A tapered punch is forced into the tube end axially, causing the tube end to flare outwardly.

Abstract: An internal swage fitting for swaging a tube. The fitting includes a tube connection region with one or more radial grooves and an expansion cavity at the end adjacent to the end of the tube to be swaged. The expansion cavity accommodates flowing tube material during the swaging process with minimal axial pressure on the fitting.

The innermost diameter of the axial bore is smaller than at least a portion of the upset of the first tube.

Abstract: A body that slides over an end, opposite end, and outer diameter of a conduit is presented. A passage through the body has a groove in which a seal is located. A portion of the conduit is expanded to create an interference fit with the passage, groove, and ends of the body. As a result, an enlarged outer diameter of the conduit axially interlocks with the groove and compresses the seal therein to create a fluid-tight seal. In one embodiment of the present invention, a second enlarged outer diameter of the conduit is displaced outward over the opposite of the body to help lock the body to the conduit. Additionally, an outside diameter of the body can accommodate grooves for retaining seals. These seals can create a sealed engagement to a housing or another fitting, to form a complete conduit connection. The body can take the form of a housing, a male fitting, or a female fitting.

Abstract: A conduit connection joint is formed to connect a tube (10) and afitting body (12) in fluid tight relation. The joint is made by axially compressing the tube (10) in a bore (14) in the fitting body (12) so as to cause formation of a first bead (52) in a bead formation area. Further axial compression of the tube (10) causes the sequential formation of an additional bead (54) in the bore (14) so as to provide engagement between the tube (10) and the fitting body (12). The engagement of the fitting body (12) and the tube (10) may be further strengthened by axially compressing and radially expanding the beads (52, 54).
