ABSTRACT:
A yard hydrant includes a head section with a nozzle, a standpipe and valve housing in traditional hydrant relationship that is constructed and assembled into an integral unit which cannot be disassembled. An operating rod with valve means reciprocates in the standpipe and a valve housing in a well known manner. The rod extends through an enlarged opening formed in the head section for which there is provided a novel two piece gland unit with one piece being a packing gland nut for seal engagement with the operating rod in a well known manner and the other piece being a concentrically larger nut that is removably mounted in said opening in a watertight relationship thereto and in pressing engagement with the packing gland nut. Removal of the gland unit permits the operating rod and any attached components to be quickly and easily withdrawn from the integral unit through the opening in the head section for servicing or repairs.
