Abstract: A breakaway coupling for fluid systems wherein interconnected coupling parts will separate upon predetermined bending or tension forces being applied to the respective parts. A bending or tension force appllied to one part axially misaligned with respect to the other part produces a pivotal movement which automatically releases the coupling connection means permitting the parts to separate without damage. Additionally, the coupling incorporates automatic release structure sensing coaxial tension forces permitting uncoupling without relative pivoting.

Abstract: An end fitting for flexible hose consisting of a body formed by two separable portions interconnected by frangible means. The fitting body includes a valve normally held in the open position permitting unrestricted flow through the fitting and upon separation of the fitting portions the valve is displaced to a closed position closing the fitting to flow therethrough.

Abstract: A valved fitting for handling flowing fluids having another valved fitting or conduit attached thereto wherein a frangible interconnection is utilized. Upon the frangible connection fracturing, such action is sensed by valve operating means for closing the valve against fluid flow producing a self-sealing of the fitting. A flapper valve is utilized to seal the valve passage insuring maximum flow characteristics with a minimum of resistance during fluid flow.The fitting utilizes unique frangible connection means wherein the connector is capable of fracturing under the influence of excessive forces imposed either axially or radially with respect to the fitting passage and flow path.
