The BMI USA 10026 is a black steel pipe nipple sized at 3 inches by 5 inches, designed for use in threaded pipe assemblies across plumbing, gas distribution, and mechanical piping systems. Fabricated from steel with a black finish, this nipple provides a durable, corrosion-resistant connection point between fittings, valves, and pipe runs. At 2.62 pounds, the fitting offers solid construction suitable for demanding trade applications. Licensed plumbers, pipefitters, and mechanical contractors routinely install this type of nipple when extending or offsetting threaded pipe runs in both new construction and retrofit work.
This black steel pipe nipple is well suited for residential and light commercial gas piping, hydronic heating systems, and general industrial pipe assemblies where threaded black steel fittings are specified. The 3-inch nominal diameter and 5-inch length make it a common choice for short offset runs and drop connections in mechanical rooms, boiler rooms, and utility spaces. It threads directly into standard NPT-threaded fittings and valves without adapters.
Designed as an OEM-style replacement or standard component for threaded black steel pipe systems using 3-inch NPT connections in plumbing, gas, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter following applicable local codes, including IFGC requirements for gas piping systems. Shut off gas supply or isolate the water system before beginning work. Apply approved thread sealant or PTFE tape rated for the intended service to all threaded connections before making up the joint. Do not over-tighten threaded connections, as this can damage fittings or crack cast components elsewhere in the assembly.
