Abstract

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).
