Bmi Usa 10578 Black Steel Pipe Nipple 18 Inches

Product Description

The BMI USA 10578 is a black steel pipe nipple sized at 18 inches in length and designed for use in threaded pipe assemblies across plumbing, gas distribution, and mechanical piping systems. Fabricated from steel with a black finish, this ready-cut nipple threads directly into fittings, valves, and other threaded connections without additional cutting or threading on site. It is a standard close-tolerance component installed by licensed plumbers, pipefitters, and mechanical contractors in both residential and light commercial applications. The black finish is typical for gas piping applications and provides a degree of corrosion resistance suitable for dry, interior environments.

This pipe nipple is suited for use in gas supply lines, water distribution, and general mechanical piping systems where a threaded, ready-cut steel nipple is required. Its 18-inch length makes it useful for spanning standard stud bays or connecting fixtures at moderate offsets. Licensed plumbers and gas fitters commonly use nipples of this type when assembling black iron gas piping runs in residential furnace, boiler, and water heater installations.

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC). Shut off the gas or water supply and depressurize the line before removing or installing any threaded pipe component. Apply an appropriate thread sealant or PTFE tape rated for the service medium — use only sealants listed for gas service on gas lines. Inspect threads for damage before assembly and do not overtighten, which can crack fittings or distort threads.
