The BMI USA 10471 is a black steel pipe nipple designed for use in threaded pipe systems across plumbing, gas distribution, and mechanical piping applications. This fitting connects two female-threaded fittings or components and serves as a short-run pipe extension within a system. Constructed from steel with a black finish, the 10471 measures 0.5 inches in diameter and 11 inches in length, making it suitable for close-quarter runs where flexibility in routing is needed. Licensed plumbers and pipefitters are the primary installers of this type of fitting in both residential and light commercial settings.
This black pipe nipple is commonly used in natural gas supply lines, propane distribution systems, water supply piping, and general mechanical systems where steel threaded fittings are specified. The black finish distinguishes it from galvanized fittings and is standard in gas-service piping per most local codes. It fits into standard threaded pipe assemblies requiring a half-inch nominal diameter run.
Designed as an OEM-style replacement or standard fitting for half-inch threaded pipe systems, compatible with any standard NPT female-threaded fitting or valve accepting a 0.5-inch nominal pipe connection.
Installation of threaded black steel pipe nipples is typically performed by licensed plumbers or gas fitters. Shut off the gas supply or water source completely before disassembling or extending any threaded pipe run. Apply an appropriate pipe thread sealant or PTFE tape rated for the intended service before threading the nipple into fittings. Follow all applicable local codes and IFGC requirements when using black pipe in gas distribution applications.
