A fluid coupling component having a valve that functions in a conventional manner when the component is connected to a mating component, but functions as a pressure relief valve when the component is in a disconnected condition. The coupling component includes a poppet and a valve, both mounted for sliding movement within a housing, and urged into engagement by a valve spring, when in the disconnected condition. A shoulder inside the housing limits movement of the poppet in a direction out of the housing, and allows sufficient internal fluid pressure to move the valve out of engagement with the poppet.
