Prier’s C-633 Series is a heavy-duty commercial wall hydrant with two unique designs: a 360° swivel that allows a simple piping orientation inside a narrow wall; and a close-coupled design for straight supply piping applications. Both designs have inlets that will connect to either 3/4” MPT or 1” FPT pipe in tight spaces. The hydrants provide flow up to 19 gal. per min. and have a box option that will allow for installation inside a 6” wall. The operating stem’s threaded ends, triple-seal stopper and worm sleeve are pinned and removable for future maintenance.
