Abstract
A adapter provides for connection of a pressure relief mechanism to a connection fitting portion of a quick connect fitting through a mating connection fitting portion and provides for movement of the pressure relief mechanism against a check valve in a hydraulic fluid conduit through a screw thread connection to the adapter. When the check valve is thus opened fluid flow is provided substantially axially through the pressure relief mechanism, thereby reducing the likelihood of disengagement of respective portions of the quick connect fitting when hydraulic fluid is present. Collection of hydraulic fluid in a vessel connected to the pressure relief mechanism is provided to allow recycling of the fluid and to prevent release of the fluid into the environment.
