Abstract
A tube coupling comprising a metal tube of relatively uniform thickness and having a radially outwardly expanded integral sleeve at one end thereof, and a radially extending tube shoulder being defined at the juncture at which the sleeve is expanded outwardly, the tube having a throughbore of a first inner diameter, and the expanded sleeve having a throughbore of a second inner diameter greater than the first inner diameter and concentric therewith. A cylindrical, hollow insert is located concentric with the axis of the tube, the insert including a radially extending annular collar at one end thereof. The collar has a tube end face abutting the radial tube shoulder and inertially welded to the tube at the interface of the tube end face and the radial tube shoulder. The insert includes at its other end a cylindrical barrel portion having hose locking and sealing means. A flexible hose is supported on the insert barrel portion and secured and sealed relative to the sleeve and the insert by the sleeve being crimped over the insert barrel portion to thereby extrude the hose into the sealing and locking grooves permanently holding the hose in compression.
