The BK MUELLER 583-120HN is a Schedule 40 black steel pipe nipple sized at 1/2 inch diameter by 12 inches long. It carries a standard 1/2 inch NPT thread on both ends and ships with a black finish coating applied over the steel body. This nipple is used to make threaded pipe connections in gas, air, and water distribution systems. Plumbers, pipefitters, and HVAC technicians install this type of fitting when extending or connecting threaded iron pipe runs. The Schedule 40 wall thickness meets typical service requirements for residential and light commercial piping applications.
This nipple is suited for use in residential and light commercial settings where threaded black iron pipe is the specified material. Common applications include natural gas supply lines, propane distribution, compressed air systems, and hydronic heating piping. It connects between threaded fittings, valves, and equipment flanges wherever a 12 inch close extension is needed in a 1/2 inch line. The black finish is standard for gas piping installations and is compatible with pipe dope and thread sealant compounds commonly used in the trade.
Designed as a standard OEM-style replacement or new-installation component for 1/2 inch Schedule 40 threaded black iron pipe systems.
Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line before removing or installing any threaded nipple. Apply an approved thread sealant or pipe dope to the male threads before making up the joint. Gas line installations must comply with applicable local codes and IFGC requirements.
