The BMI USA 10089 is a black steel pipe nipple measuring 6 inches in diameter and 12 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other piping components in a run. This nipple is manufactured from steel with a black finish, making it well suited for gas distribution, steam, and industrial piping applications where a coated finish provides basic corrosion resistance in dry service environments. Licensed plumbers and pipefitters install this type of fitting as part of roughed-in gas or fluid piping systems in both residential and light commercial construction.
This 6-inch by 12-inch black steel nipple is commonly used in gas supply lines, compressed air systems, and general-purpose plumbing runs where threaded steel pipe is specified. The 12-inch body length places it in the close-to-long nipple range, providing enough extension to clear structural framing, valves, or manifold assemblies. It is a standard component in gas meter sets, boiler rooms, and mechanical rooms where rigid steel pipe construction is required by code.
Designed as an OEM-style replacement or new-install component for threaded steel pipe systems using 6-inch nominal black steel pipe and standard NPT threaded fittings.
Installation of black steel pipe nipples in gas service must be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off all gas or fluid supply and verify zero pressure in the line before threading or replacing any nipple. Apply an approved pipe thread sealant or PTFE tape rated for the intended service to all threaded connections. Inspect threads for damage before installation and do not use a nipple with crossed or deformed threads.
