Applications
Brass ASTM B584 C84800 is used for low-pressure valves, air- and gas-line fittings, plumbing fittings and faucets. Hardware applications include stops, washers and other general fittings. Other cast components used in this material family include valve bodies, pump-related parts, shaped connections and hardware and enclosure components.
Applications include plumbing, water-handling equipment, building services and industrial fluid-control assemblies. A plumbing use does not itself establish drinking-water certification or a finished component pressure rating.
