The BMI USA 10979 is a black steel pipe nipple sized at 2 inches in diameter and 24 inches in length. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and other components in a piping system. This nipple is manufactured from steel with a black finish, making it suitable for gas distribution, oil lines, and similar non-potable fluid systems. At 7.16 pounds, it is a solid, full-weight schedule pipe section intended for professional installation in commercial and residential mechanical systems.
This pipe nipple is commonly used in gas piping, steam, and hydronic heating systems where a threaded black steel connection is required. Plumbers, pipefitters, and HVAC technicians install black steel nipples when making up gas manifolds, branch connections, and riser assemblies. The 24-inch length provides flexibility for installations where a longer run between fittings is needed without an additional coupling.
Designed as a standard replacement or new-installation black steel pipe nipple compatible with 2-inch NPT threaded fittings and valves used in residential and commercial gas, steam, and hydronic piping systems.
Black steel pipe nipples are installed by licensed plumbers or pipefitters in accordance with local mechanical codes and the International Fuel Gas Code (IFGC) for gas piping applications. Always shut off and depressurize the line before threading or removing any pipe section. Use an appropriate thread sealant rated for the intended service medium, and inspect threads for damage before making up connections. Do not use black steel pipe for potable water systems.
