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.
