The BMI USA 10171 is a black steel pipe nipple designed for threaded pipe assemblies in plumbing, gas, and mechanical systems. Measuring 1/8 inch in diameter and 11 inches in length, this nipple serves as a short threaded connector between fittings, valves, and other piping components. The black finish results from a hot-process treatment that provides a base level of corrosion resistance suitable for dry or low-moisture applications. Licensed plumbers and pipefitters install this type of nipple in both residential and light commercial systems.
This nipple is well suited for low-pressure gas distribution lines, black iron piping systems, and general mechanical plumbing where 1/8-inch threaded connections are specified. The 11-inch length makes it useful in situations where standard close or short nipples do not reach between fittings. Typical applications include branch connections, appliance gas supply lines, and threaded pipe framework in mechanical rooms and utility spaces.
Designed as a standard NPT-threaded replacement or new-installation nipple for 1/8-inch black iron piping systems used in residential and light commercial gas and plumbing applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the application. Shut off the gas or water supply and depressurize the line before removing or installing any threaded pipe component. Apply an approved pipe thread sealant or PTFE tape rated for the intended service to all threaded connections before assembly. Do not over-tighten threaded fittings, as this can damage threads or crack adjacent fittings.
