Patent ID: 8622085

Claim:
A system, comprising: a hydraulic connector configured to couple hydraulic lines in a mineral extraction system, the connector comprising: a first coupling configured to be secured to a first hydraulic line, wherein the first coupling comprises a first valve in a first fluid pathway, and the first valve is configured to selectively close a first opening in the first fluid pathway; and a second coupling configured to be secured to a second hydraulic line, wherein the second coupling comprises a second valve in a second fluid pathway, and the second valve is configured to selectively close a second opening in the second fluid pathway; wherein the first and second valves are automatically biased to close the first and second openings, respectively, to resist ingress of an external fluid when the first coupling is not mated to the second coupling, and the first valve is configured to automatically open the first opening when the first coupling is not mated to the second coupling and a first pressure of a first fluid within the first hydraulic line exceeds a second pressure of the external fluid by a threshold value.
