B K/mueller Inds(import) 586-035HC Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 586-035HC is a black steel pipe nipple measuring 1-1/4 inches in diameter by 3-1/2 inches in length. Pipe nipples are short sections of threaded pipe used to connect two fittings, valves, or other piping components in a run. This nipple is finished in black, indicating it is made from black steel rather than galvanized material, making it a standard choice for gas piping, steam systems, and other non-potable applications. Plumbers, pipefitters, and gas service technicians regularly install this type of fitting as part of both new construction and repair work.

This nipple is suited for residential and light commercial piping systems where a short close nipple or standard-length connection is required between threaded components. Common applications include natural gas supply lines, propane distribution, steam heating systems, and industrial fluid conveyance where black steel pipe is the specified material. It ships in a package quantity of 5 units, making it practical for contractors stocking truck inventory or completing multi-connection installations.

Installation Notes

Installation is typically performed by a licensed plumber or gas fitter working under applicable local codes, including IFGC requirements for gas piping. Shut off the gas supply or drain the system before removing or installing threaded pipe components. Apply an approved thread sealant or pipe thread compound rated for the intended service medium before making up threaded connections. Do not over-tighten threaded fittings, as this can damage threads or crack cast fittings downstream.
