B K/mueller Inds(import) 585-040HN Black Pipe Nipple 1x4

Product Description

The B K/MUELLER INDS(IMPORT) 585-040HN is a black steel pipe nipple measuring 1 inch in diameter by 4 inches in length. Pipe nipples are short sections of threaded pipe used to connect two fittings, valves, or other piping components. This nipple is finished in black, indicating a standard black iron or black steel construction suited for gas distribution, fire suppression, and general industrial piping systems. Licensed plumbers, pipefitters, and gas technicians install these as part of low- and medium-pressure pipe assemblies in both residential and light commercial applications. Each unit ships in a package of 10.

This nipple is used in threaded pipe systems where a short, rigid connection is needed between two female-threaded components. Common applications include natural gas and propane distribution lines, steam systems, water supply rough-in, and industrial fluid transport. The black finish makes it the standard choice for gas piping installations where galvanized fittings are not permitted by local code. Each package contains 10 nipples, making this suitable for multi-connection jobs or stocking service vehicles.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the pipe system completely before removing or installing any threaded components. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all threaded connections. Do not overtighten connections; use a pipe wrench with appropriate leverage for the fitting size.
