The ASC Engineered Solutions 830047809 is a black steel pipe nipple measuring 3 inches in diameter by 9 inches in length. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and equipment in piping systems. This nipple is manufactured from black steel, making it well suited for gas distribution, fire suppression, and industrial fluid conveyance applications where galvanized or plastic fittings are not appropriate. At 4.97 pounds, it is a solid, full-weight fitting intended for permanent or semi-permanent installations. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this type of fitting.
This black steel nipple is appropriate for use in residential and commercial gas piping systems, steam and hydronic heating systems, and industrial process piping. The 3-inch nominal pipe size suits larger-diameter distribution runs where flow capacity is a priority. It is commonly installed at equipment connections, headers, and branch takeoffs where a short, rigid threaded section is needed to close a gap between two threaded components.
Designed as a standard threaded black steel pipe nipple compatible with 3-inch NPT fittings, valves, and threaded pipe connections in gas and mechanical piping systems.
Installation of black steel pipe nipples in gas systems must be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) and local amendments. Shut off and verify that gas or fluid supply is fully isolated and depressurized before making any threaded connections. Apply a code-approved pipe thread sealant or PTFE tape rated for the service medium to all threaded joints. Do not use black steel fittings in potable water systems.
