Abstract: A unique fluid connector is disclosed that quickly connects a tube within a housing bore, while providing a strong, fluid tight seal. The tube has axially spaced radially greater diameter upset portions with a sleeve and a locking member trapped between the upset portions. The locking member includes resilient arms which secure it within the housing bore. The sleeve has a notch at an inner axial end which abuts the inner upset portion to retain the tube within the bore. An O-ring is positioned axially inwardly of the upset portion. The sleeve and the inner upset portion both abut the O-ring to provide a fluid tight seal between the tube and the housing. In a unique method, a tube unit is assembled by forming the outer upset portion on the tube. The locking member and sleeve are then moved onto the tube. The inner upset portion is then formed on the tube to secure the locking member and the sleeve on the tube. An O-ring retaining portion is then formed on the tube, and the O-ring is positioned onto the tube. The assembled tube unit is then inserted into the housing bore. Further, a flexible tube may be connected to an outer end of said tube by crimping a metal ferrule radially inwardly.

Abstract: A connector for receiving a tube end having at least one radially enlarged upset. The connector comprises a hollow female connector body and a retainer disposed in the connector body. The retainer has an annular inner base ring defining a cylindrical surface to receive the tube end. The retainer further defines compressive members. The base ring has a limit surface facing the compressive members and a chamfer intersecting the limit surface and the cylindrical surface. The compressive members define an inner diameter and a space between the limit surface and the compressive members for securing the radially enlarged upset in the connector body. The inner diameter of the compressive members is at least as large as the diameter of the intersection of the chamfer with the limit surface.

Abstract: A release sleeve used with quick connect tube connectors includes a plurality of planar surfaces at an outer peripheral surface which bias retainer legs radially outwardly to allow removal of a tube. The use of planar surfaces provides a greater contact area than prior art release sleeves, thus reducing the amount of force necessary to allow tube removal. In a further feature of the present invention, the release sleeve has grooves at an outer peripheral surface which allow passage of indicator legs such that the release sleeve may be used in combination with an indicator used to give an indication that a tube is fully connected.

Abstract: A coupling assembly comprising a female connector body, a male member, a retainer and a dust barrier. The female connector body defines a bore extending axially inward into the connector body from an entrance. A radial face is defined in the bore axially inward of the entrance. The male member is received within said bore. The male member is formed at the end of a tube and includes a projection extending radially from the tube. The retainer has at least two locking beams extending between the radially extending projection and the radial face to retain the male member in the bore. The locking beams defines a slot between the locking beams. The dust barrier is slidably mounted on the tube. The dust barrier has at least one extension insertable within the slot so as to prevent inadvertent radially inward movement of the locking beams. Wherein upon sliding the dust barrier toward the female connector body, the dust barrier encloses the bore so as to prevent foreign material from entering the coupling assembly.
