ABSTRACT:
A frangible fluid conduit fitting particularly suitable for servicing aircraft wherein the fitting is attached to an aircraft service bulkhead coupling. The fitting consists of two parts, one attached to the supply hose and the other attachable to the bulkhead coupling. The fitting parts are maintained in a sealed assembly relationship by a frangible connector having two separate frangible sections. One frangible section fracturing and releasing the fitting parts under excessive bending forces while the other frangible structure releases upon excessive tension forces being imposed upon the fitting.
