The C-633 Series is a heavy-duty commercial wall hydrant designed specifically with contractors, engineers and wholesalers in mind. It includes two designs; one that includes a 360-degree swivel that allows a simple piping orientation inside a narrow wall (part number C-633NSV), and another that consists of a close-coupled design for straight supply piping applications (part number C-633NCC, C-633PCC or C-633VCC). Both designs have inlets that will connect to 3/4-inch MPT or 1-inch FPT pipe in tight spaces. These hydrants are key operated, code approved, flow up to 19 gpm and have a box option that will allow for installation inside a 6-inch wall.
