Abstract: The claimed universal polymeric molded fire hydrant is lightweight, weather resistant and will meet the UL, FM, NFPA and AWWA standards established for conventional metallic hydrants. Polymeric fire hydrants will also exceed standard performance expectations by eliminating rusting, binding, cracking and the associated need for periodic painting and lubrication. This polymeric fire hydrant costs less to produce than traditional metallic models providing significant costs savings to commercial and residential developers as well as municipalities. The inherent light weight nature of the units will reduce manpower and heavy equipment required to install it. This hydrant can be manufactured to resemble all existing traditional hydrant designs and performance specifications and will allow for future design modifications as future performance specifications and designs evolve.

In one preferred form, rounded elbow pipe segments are threaded onto the hose connections of an existing fire hydrant and are rigidly secured in place thereon to provide upwardly oriented fire hydrant hose connections, and/or protective enclosure components are attached to the existing fire hydrant to provide an open-walled cage-like structure that maintains proper obstruction-free access space in regions that extend about the hydrant's hose connections so that fire hoses easily can be coupled to the hydrant.

Abstract: A three-way wet barrel fire hydrant includes an enlarged intermediate barrel section, which effectively reduces pressure loss in the fire hydrant. The hydrant barrel is formed by an improved sand molding process which requires the mold parting line of the barrel to be selected to coincide with the centerline of the upper nozzle opening. In this manner, a pattern which forms the sand mold may be removed cleanly from the molding sand, thereby eliminating the need of multiple side cores during the casting process.
