The BMI USA 10125 is a black steel pipe nipple designed for low-pressure pipe assemblies in gas, air, and water distribution systems. Measuring 1/8 inch in diameter and 2.5 inches in length, this nipple provides a compact, threaded connection between fittings, valves, or other pipe sections. The black finish results from a hot-applied coating that offers basic surface protection. At 0.05 pounds, it is a lightweight component suited for tight-space installations. Licensed plumbers, pipefitters, and HVAC technicians regularly specify black steel nipples for their durability and thread integrity in threaded pipe systems.
This nipple is commonly used in residential and light commercial applications including natural gas supply lines, compressed air distribution, and water piping assemblies. The 1/8 inch size is typical in branch connections, instrumentation ports, and pilot gas lines where a small-diameter threaded fitting is required. It threads into standard NPT fittings and is a routine stock item for service trucks and shop inventory.
Designed as a standard-thread replacement or new-installation nipple for 1/8 inch NPT threaded pipe systems in gas, air, and water distribution applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IPC and IFGC requirements where applicable. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or distort thread engagement.
