B K Mueller 583-050HN Black Pipe Nipple 1/2x5 Inch 15 Pack

Product Description

The B K Mueller Industries 583-050HN is a black steel pipe nipple measuring 1/2 inch in diameter and 5 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other threaded components in a piping system. This nipple ships in a package quantity of 15 units, making it a practical choice for contractors stocking up for multiple rough-in or repair jobs. Plumbers and pipefitters install black steel nipples in gas distribution, compressed air, and general industrial piping applications where galvanized or plastic fittings are not specified.

Black steel pipe nipples like the 583-050HN are commonly used in residential and light commercial gas piping systems, including natural gas and propane distribution lines inside buildings. They are also found in fire suppression systems, air lines, and hydraulic systems where threaded black iron pipe is the standard material. The package quantity of 15 makes this a cost-effective option for service trucks, wholesale counters, or multi-unit installations requiring consistent short-run connections.

Installation Notes

Black steel pipe nipples are installed by licensed plumbers or pipefitters following local mechanical and fuel gas codes, including IFGC requirements for gas piping systems. Always shut off the gas supply or depressurize the line before making or breaking threaded connections. Apply an approved thread sealant or PTFE tape rated for the service fluid before assembly. Do not overtighten threaded connections, as this can crack fittings or damage threads.
