Abstract
A coupling assembly includes a female coupler selectively interconnected to a male coupler to provide sealing engagement. In one embodiment, the female coupler and the male coupler are secured together by a pressure activated locking assembly which prevents disengagement of the male and female coupling until the internal pressure in the coupling is reduced to a predetermined level.
