ABSTRACT:
A tube fitting assembly is provided for a gas burner. The assembly includes a pre-deformed tube connector having first and second ends. At least one of the ends is provided an annular sealing bead formed by compressing and cold working at least two intermediate annular beads together. A first coupling member is provided defining a cavity and having a shaped seating surface adapted to sealingly engage a cooperating surface of the annular sealing bead. A second coupling member is provided rotatably and slidably disposed on the pre-deformed tube connector and is adapted to mate with the first coupling member.
