US Patent 7802325 Hartford loop manifold assembly for bathing vessels

Hartford loop manifold assembly installed in operable communication with an air control assembly in a whirlpool bathing system. The manifold assembly includes a tubular manifold housing having a coupling member in intussusceptible relation therewith. The manifold housing has an elongate body and an elongate wall coextensive with an upper body proximate extent and a lower body distal extent thereof. The elongate wall includes an internal manifold wall delineating a reception lumen that accommodates insertion of the coupling member therein. The internal manifold wall is disposed by a predetermined distance from an external manifold wall in parallel therewith to define a flow area therebetween. The external manifold wall has at least one outlet depending generally normally therefrom. Each outlet has a lumen defined therethrough for unoccluded fluid communication between each manifold flow area and at least one conduit detachably coupled to each outlet extent.
