Abstract
A gas tube assembly includes a first cylindrical metal gas supply tube terminating in a first end. An annular coupling nut with a central opening receives the first end of the tube and has a cylindrical counterbore which extends axially inward of the central opening about the first end of said tube. The counterbore terminates in a transversely extending shoulder. A radially outward extending circumferential bead formed integrally with the tube is located within the counterbore adjacent the first end of the tube and is positioned in engagement with the transversely extending shoulder. Connected to the tube is a gas burner orifice nozzle having an inlet end with a transverse end face and an axially extending throughbore. The throughbore has an inlet end which receives the first end of the tube. An outer terminal end of the nozzle defines a gas outlet orifice which is substantially smaller in diameter than the diameter of the bore at the inlet end. A circumferential exterior portion of the nozzle about the inlet end is threadedly received in the coupling nut with the end face sealingly engaging the bead.
