The BMI USA 10490 is an assorted pack of 66 black steel pipe nipples, each measuring 6 inches in length. These nipples are manufactured from steel with a black finish, making them well suited for low-pressure gas, air, and water distribution applications common in commercial and residential plumbing and mechanical systems. The pack format reduces procurement time on larger jobs where multiple fittings are needed at once. Licensed plumbers and pipefitters typically specify black steel nipples where galvanized or plastic fittings are not permitted by code. The 14.46-pound pack weight reflects the solid steel construction of the full 66-piece assortment.
Black steel pipe nipples in the 6-inch length are a staple in gas distribution piping, fire sprinkler branch lines, compressed air systems, and general-purpose black iron pipe assemblies. They are installed in residential and light commercial settings alike, connecting valves, fittings, and equipment in threaded pipe systems. The assorted-quantity pack format is practical for plumbing supply rooms, service vehicles, and job-site staging where having spare nipples on hand prevents delays.
Designed as an OEM-style replacement and standard-stock pipe nipple for threaded black iron pipe systems using NPT connections in plumbing, gas, and mechanical piping applications.
Black steel pipe nipples are installed by licensed plumbers or pipefitters following applicable codes such as the IPC and IFGC. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or tape rated for the intended service medium before making up the joint. Do not overtighten threaded connections, as this can crack fittings or distort threads.
