Bmi Usa 10049 Black Steel Pipe Nipple 4x7 Inch

Product Description

The BMI USA 10049 is a black steel pipe nipple measuring 4 inches in diameter and 7 inches in length. Pipe nipples are short threaded sections used to connect fittings, valves, and other pipe components in a run. This nipple carries a black finish, which is standard for low-pressure gas distribution and non-potable fluid piping systems. At 5.55 pounds, it is a solid, full-weight fitting suited for demanding mechanical and plumbing applications. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians frequently use black steel nipples in gas supply roughing work.

Black steel pipe nipples like the 10049 are used across residential and light commercial installations. Common applications include natural gas and propane supply lines, steam and hydronic heating systems, and industrial fluid transfer. The 4-inch diameter and 7-inch length make this a commonly specified size for gas header assemblies, boiler connections, and mechanical room piping where a short close-coupled extension is needed between components. Its steel construction handles the thermal and mechanical stresses typical in these environments.

Key Features

• Black finish suitable for gas and non-potable piping applications
• Steel construction provides strength and durability under pressure and heat
• 4-inch diameter x 7-inch length for close-coupled fitting connections
• Threaded ends for standard NPT fitting assembly
• Solid weight at 5.55 pounds indicating full-thickness wall construction

Compatibility

Designed as a standard NPT-threaded black steel pipe nipple for use with compatible 4-inch pipe fittings, valves, and couplings in gas, steam, and fluid piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as relevant. Shut off and depressurize the line before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape rated for the service medium before assembly. Inspect threads for damage before installation and do not overtighten, as this can crack fittings or distort threads.
