The present invention is a plumbing accessory having a sprayer valve, hose and connector assembly which conveniently connects to the aerator threads on a sink faucet. The connector provides a swivel connection during attachment so the assembly may be attached without twisting the hose. The present connector comprises three parts. First, there is a generally cylindrical, hollow basket-like or cup-like structure which is threaded at its open top end, preferably both on the inside and outside perimeters. The bottom end of the cup is closed except for a central, generally circular orifice. Second, there is a generally cylindrical insert structure which fits smoothly, but not loosely inside the cup. The insert has a flat bottom which rests upon the top of the bottom closed end of the cup. The insert is also generally hollow, providing a central opening which extends from near the open top of the inside of the cup through its closed bottom. At the bottom of the insert is a generally cylindrical, hollow extension, which projects down through the orifice in the bottom of the cup. The distal end of the extension, preferably with stepped outside edges, is adapted for fitting into the proximal end of a plastic or rubber hose in conventional fashion. Third, there is a generally cylindrical sealer washer which also fits inside the cup, and rests smoothly, but not loosely, on top of the insert. The sealer washer also has a central, generally circular orifice which is generally co-extensive with the central opening in the top of the insert. |
