The BMI USA 10850 is a black steel pipe nipple used to connect threaded pipe sections in plumbing, gas, and mechanical piping systems. Manufactured from steel with a black finish, this nipple measures 1.5 inches in diameter and 5 inches in length. It threads directly into fittings, valves, and equipment on both ends, serving as a short run connector in low-pressure fluid and gas distribution. Licensed plumbers and pipefitters install this type of fitting in residential and commercial applications where a durable, code-compliant threaded connection is required.
This nipple is suited for use in gas supply lines, water distribution, and mechanical room piping where standard black iron pipe fittings are specified. The black finish is typical for gas service and distinguishes the fitting from galvanized water supply components. It is commonly installed in boiler rooms, mechanical chases, and utility spaces as part of a threaded piping assembly.
Designed as a standard threaded black iron pipe nipple compatible with 1.5-inch NPT fittings, valves, and threaded pipe in residential and commercial plumbing and gas piping systems.
Installation of threaded pipe nipples in gas service should be performed by a licensed plumber or pipefitter in accordance with local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as applicable. Shut off the gas or water supply and depressurize the line before making or breaking any threaded connection. Apply an appropriate thread sealant or listed pipe thread compound to all male threads before assembly. Do not over-tighten threaded connections, as this can damage fittings or crack pipe threads.
