A quick connect coupling (20) for fluid tight connection to a threaded fluid port (22). A body (26) of the quick connect coupling (20) having a cylindrical, externally threaded first end (28) defining an axially extending passage (29) into the coupling body (26). Axially slidable sleeve (42) being mounted on the outside of the coupling body (26) for slidable motion between a seal unassisted position and a seal assisted position, the axially slidable sleeve (42) forcing against an elastomeric seal (30) in the seal assisted position so as to provide a fluid tight seal between an end of the fluid port (22) and the coupling (20).

A quick connect coupling for fluid tight connection to a threaded fluid port, comprising: (a) a coupling body, the coupling body having a cylindrical, externally threaded first end, the first end defining a passage extending axially into the coupling body from the first end; (b) elastomeric sealing means circumferentially surrounding the first end of the coupling body for abutting an end of the fluid port upon threading the first end into the fluid port; (c) external, axially slidable sleeve slidable between an unassisted seal position and a pressure assisted seal position, a first end of the sleeve including shoulder means for engaging the elastomeric seal means in the pressure assisted seal position, an opposite second end of the sleeve cooperating with retention means for retaining the sleeve on the coupling body; the axially slidable sleeve and the coupling body cooperating to define a cavity there between, passage means extending from the axially extending passage to the cavity for placing the cavity in fluid communication with the axially extending passage, the axially slidable sleeve and the coupling body further cooperating to cause an unbalanced force on the sleeve when subjected to fluid pressure, a resultant net force being axially directed on the sleeve in the direction of the fluid port, whereby entrance of fluid under pressure from the fluid port into the cavity forces the sleeve forward into engagement with the elastomeric seal means thereby forcing the elastomeric seal means against an end of the fluid port so as to form a fluid tight seal between the quick connector and the fluid port; and (e) secondary seal means proximate the second end of the sleeve for providing a fluid tight seal between the sleeve and the coupling body.
