Provided is a coupling including female 12 and male couplers 14 configured to be coupled by first and second stage connections. In the first stage connection, a plurality of detents 78 in the female coupler 12 are urged into a detent recess 150 in the male coupler 14 to coupled the female 12 and male couplers 14. To make the second stage connection after the first stage connection has been made, threads 66 on the male coupler 14 are mated with threads 64 on a release sleeve 22, which causes valves disposed in the female and male couplers to move to an open position to allow fluid flow through the coupling. In this way, reduced force is employed to engage the female and male couplers while avoiding contact between the detents and the threads on the male coupler, thereby preventing the detents and threads on the male coupler from damaging one another. |
