ABSTRACT:
A quick disconnect coupling that is used to interconnect a dispensing hose from a reactor tank to any one of a plurality of charge tanks to facilitate the transfer of ingredients from the charge tanks to the reactor tank. Each charge tank has an outlet pipe with an annular flange thereon that supports a larger concentric rigid tube which projects outwardly beyond the outlet pipe. The dispensing hose has a rigid pipe connected thereto which is adapted to be received by the rigid tube and into abutting contact with the outlet pipe. An inflatable annular tube is secured to the rigid tube and encompasses the outlet pipe and the rigid pipe upon reception of the rigid pipe by the rigid tube so that upon inflation of the inflatable annular tube the coupling interconnects and seals the outlet pipe, the rigid tube and the rigid pipe.
