B K Mueller 583-120HN Black Pipe Nipple 1/2 X 12 in

Product Description

The B K Mueller Industries 583-120HN is a black steel pipe nipple sized at 0.5 inches nominal diameter by 12 inches in length. Pipe nipples are short threaded sections of pipe used to connect two female-threaded fittings or to extend a pipe run within a system. This nipple is finished in black, indicating it is uncoated steel without galvanization, making it appropriate for gas distribution, steam, and air piping applications. It is installed by plumbers, pipefitters, and HVAC technicians working on low-pressure piping systems in residential and light commercial settings.

This nipple is suited for use in gas supply lines, steam systems, compressed air lines, and general plumbing pipe assemblies where a 0.5-inch nominal threaded connection is required. The 12-inch length makes it useful in close-quarters installations where a longer close nipple would fall short but a full pipe section is unnecessary. Sold in a package quantity of 15, it is well-suited for contractors stocking common nipple sizes on the truck or in a shop inventory.

Installation Notes

Black steel pipe nipples are installed by licensed plumbers, pipefitters, or HVAC technicians. Shut off and depressurize the piping system fully before removing or installing any threaded components. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before making up threaded connections. Work must comply with applicable codes such as the IFGC for gas piping or IPC for plumbing applications.
