ABSTRACT:
A quick connect coupling connects a first fluid conduit to a second fluid conduit. The quick connect coupling includes a first single or multi-layer tube which is either metal or plastic and has a wall expanded radially outwardly adjacent a longitudinal end to define an integrally formed female portion of the coupling. The expanded end has at least two apertures extending through the wall adjacent the longitudinal end of the tube. A second tube which is either metal or plastic and has a first end with a radially outwardly projecting annular flange spaced longitudinally from the first end. The first end and the annular flange are engageable within the expanded end of the first tube. The first end of the second tube defines the male portion of the coupling. An elongated housing member has an outer periphery engageable within the expanded end of the first tube and has an aperture extending longitudinally therethrough for fluid communication between the first and second tubes. The housing member has an enlarged inner diameter for receiving the first end of the second tube therein. Sealing members are carried by the housing member and are insertable within the expanded end of the first tube with the elongated housing member. A lock member holds the elongated housing member in place within the expanded end of the first tube and operably engages with the apertures formed through the wall of the expand end of the first tube and the outwardly protruding annular flange of the second tube. An optional internal check valve can be provided within the elongated housing member.
