B K Mueller 585-055HC Black Pipe Nipple 1x5.5 in

Product Description

The B K Mueller Industries 585-055HC is a black steel pipe nipple sized at 1 inch diameter by 5.5 inches in length. Pipe nipples are short sections of externally threaded pipe used to connect fittings, valves, and equipment in piping assemblies. This nipple is finished in black, indicating plain steel without galvanizing, which is standard for gas distribution piping and certain low-pressure fluid systems. Licensed plumbers and gas fitters install this type of fitting in residential and light commercial applications. It ships in a package quantity of 10 units.

This black pipe nipple is commonly used in natural gas and propane distribution lines, as well as low-pressure steam, air, and water systems where galvanized or stainless materials are not required. The 1-inch diameter makes it suitable for branch and main-line connections in residential gas appliance installations, boiler rooms, and mechanical rooms. It is also used in industrial and commercial piping layouts where threaded black iron fittings are the specified system standard.

Installation Notes

Black pipe nipples of this type are installed by licensed plumbers or gas fitters using pipe wrenches and appropriate thread sealant or pipe-thread compound rated for the intended service. Shut off gas supply or depressurize the system before making any threaded connections. Follow local codes including IFGC and IPC requirements for thread engagement, support spacing, and sealant compatibility with the conveyed medium. Do not use black steel nipples in systems requiring corrosion-resistant materials unless confirmed compatible by the system designer.
