The BMI USA 10042 is a black steel pipe nipple measuring 3.5 inches in length, designed for use in threaded piping systems across plumbing, gas, and mechanical applications. Black steel pipe nipples are standard fittings used to connect sections of pipe or transition between fittings, valves, and equipment. This nipple is manufactured from steel with a black finish, which is the industry-standard coating for gas supply lines and general industrial piping. Installation is typically performed by licensed plumbers, pipefitters, or gas technicians working on low-pressure distribution systems.
This fitting is suited for residential and light commercial piping installations where a short threaded connection is required. Common applications include natural gas and propane supply lines, steam and water distribution systems, and mechanical room piping. The 3.5-inch length makes it a practical close nipple alternative where a slightly extended reach is needed between fittings or at equipment connections.
Designed as an OEM-style replacement or standard fitting for threaded steel pipe systems using NPT connections in plumbing, gas, and mechanical piping applications.
Installation should be performed by a licensed plumber or gas technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC). Always shut off the gas or water supply and relieve system pressure before removing or installing threaded fittings. Apply an appropriate thread sealant or listed pipe tape to all male threads before assembly. Do not overtighten threaded connections, as this can damage fittings or compromise the seal.
