Bmi Usa 10550 Black Steel Pipe Nipple 3/4 X 5 Inch

Product Description

The BMI USA 10550 is a black steel pipe nipple used to connect sections of threaded pipe in gas, water, and industrial piping systems. At 3/4 inch diameter and 5 inches in length, this nipple provides a rigid, close-fit connection between fittings, valves, and pipe runs. The black finish is standard for gas line applications and low-pressure industrial service. Licensed plumbers and pipefitters install this nipple as part of new construction rough-in and service replacement work on threaded iron pipe systems.

This nipple fits standard threaded iron pipe applications in residential and light commercial environments. Common uses include natural gas and propane distribution lines, steam and hot water heating systems, and general-purpose industrial pipe assemblies where a 3/4 inch male-threaded connection is required at a 5-inch span. The black finish distinguishes it from galvanized fittings and is appropriate where galvanized material is not recommended, such as certain gas service connections.

Key Features

• Black finish suitable for gas line and low-pressure industrial service
• Steel construction provides strength and durability in threaded pipe assemblies
• 3/4 inch diameter with 5-inch body length for close-fit runs between fittings
• Male NPT threads on both ends for standard threaded pipe compatibility
• Lightweight at 0.43 pounds for easy handling during installation

Compatibility

Designed as a standard replacement or new-installation nipple for 3/4 inch NPT threaded pipe systems in residential and light commercial plumbing and gas piping applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable local codes, including IPC and IFGC requirements for threaded pipe assemblies. Shut off the gas or water supply and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the service type before threading the nipple into fittings. Do not over-tighten, as this can damage threads or fittings.
