An aluminum cast fire hydrant quick connector enables firefighters to connect their hoses to the main body of the hydrant. A water hydratant has two parts, the main body, or barrel, and the lower, outlet portion, or spool. These parts may be one piece or be cast in two pieces.
A cast iron or aluminum fire hydrant quick connector is a permanent connection to a hydrant. These fire hydrants are often equipped with female NST threads, which are matched to Storz connections. Some manufacturers produce removable adapters that thread directly onto the nozzle of the fire hose. Other adapters are permanently affixed and require only a few tools to install.
The process to manufacture an aluminum cast fire hydrant quick connector begins with machining a piece called a "core". This piece is a mold that is molded by machine. After the mold is machined, the hydrant's core is then inserted into the two halves of the block. The sand is filled into the cavity and the lathe starts the process of turning the mold. The process is repeated for each outlet.
