ABSTRACT:
A frangible fluid fitting of the crash-worthy type utilizing a detent holding a self-closing valve in the open position. The detent engages a plurality of balls confined in a recess circumscribing the fitting attachment surface whereby only partial fracture of the fitting in any direction causes the self-sealing valve to close. One embodiment of the fitting permits both gravity and pressurized tank filling with automatic valve closing when the tank is full during pressurized filling.
