Beschreibung
Zusammenfassung:	The invention provides a fluid tight coupling for securing the spout of fuel dispensing nozzles to the nozzle body and utilizes a metallic annular gland mounted on the upstream end of the spout and positioned thereon by the engagement of a knurled band on the spout with its inner surface by mechanical expansion of the spout, the gland being outwardly shaped and positioned on the spout to be tightly engaged and compressed between tapered surfaces and the body outlet nipple rim and the spout securing clamp nut, with the downstream portion of the gland compressed thereby into tight sealing engagement with a smooth surface portion of the spout to effect a tight fluid seal.
