An insertion indicator for a metal quick connector assembly includes an annular base adapted to be releasably received within the mouth of a female connector component's axial bore, such that the male end form of the connector assembly's male component, including an external flange thereon, is insertable through the indicator's base into the axial bore. The indicator further includes two legs projecting both axially and radially-inwardly from its base so as to extend deeper within the female component's axial bore than the 'locking' abutment surfaces of a retainer, also disposed within the bore, when the indicator is releasably received therein. Each leg is resiliently radially yieldable so as to permit passage of an external flange or upset bead on the male component through the indicator, whereupon the free end of each leg rebounds to provide an axially-disposed surface with which the indicator may thereafter be operatively ejected through engagement with the male component's upset bead upon slight retraction of the male component from within the bore.

Pop off insertion indicator for metal quick connectors

A retainer for releasably locking the male and female component of a quick connector together. The retainer is releasably insertable into a transverse bore formed in the female component and includes an edge slidable over a radial flange on the male component only when the male component is fully coupled in an axial bore in the female component. The engagement of the edges and the radial flange on the male component permits full insertion of the retainer into the transverse bore in the female component around the male component to lock the male component and female component together. Lock projections on the retainer engage grooves in the housing to releasably lock the retainer in a partially inserted, shipping position in the transverse bore in the female component and engage exterior lock surfaces on the housing on full insertion of the retainer to lock the retainer and the fully inserted male component to the female component.

Quick connector with snap-on retainer

A quick connect fluid coupling equipped with a check valve and a service valve includes a housing that has a primary passage and an auxiliary passage arranged in a T-shape construction. The primary passage is provided with a check valve and an outlet end adapted to receive a male connector member in a locking engagement. The outlet end is arranged at 90.degree. with the inlet end of the primary passage. The auxiliary passage is equipped with a service valve adapted for receiving a fluid pressure detecting head at an outlet end and shares the same inlet end with the primary passage.
