Abstract
An end fitting closes at least one end of a passageway having an external periphery and an internal periphery to be cast-in-place within a part. A fitting body has at least one elongated, blind-ended aperture formed therein. The aperture is defined at least in part by a first surface having a complimentary shape with respect to the external periphery of the cast-in-place passageway for receiving an end of the passageway disposed extending at least partially therein to close the passageway during casting of the part. The fitting body is composed of material essentially identical to material being used during casting of the part. The fitting body is positionable within a casting mold for forming the part to be cast, such that machining the cast part after casting opens the blind-end of the fitting to allow fluid flow through the passageway cast-in-place within the part. The end fitting may include a shaped aperture, such as a hexagonal shape or oval shape, for receiving a complimentary shaped nut on the conduit or complimentary shaped passageway to provide orientation of the passageway with respect to the fitting when connected thereto.
