B K Mueller 584-015HN Black Steel Pipe Nipple

Product Description

The B K Mueller Industries 584-015HN is a black steel pipe nipple sized at 0.75 inches (nominal 3/4 inch) by 1.5 inches in length. Pipe nipples are short threaded pipe sections used to connect two female-threaded fittings or valves in a piping run. This nipple is finished in black, indicating standard carbon steel construction without galvanizing, which is typical for gas distribution, compressed air, and general plumbing applications. Plumbers, pipefitters, and gas line installers regularly use close and short nipples like this one to make tight offset connections in tight spaces. This unit ships in a package quantity of 15 pieces.

This nipple suits residential and light commercial piping systems where a short, threaded male-to-male connection is required. Common applications include natural gas and propane distribution lines, steam and hot water heating systems, compressed air headers, and industrial process piping. The 3/4-inch nominal thread size is one of the most frequently used sizes in residential gas and plumbing rough-in work, making this a standard stocking item for service trucks and supply rooms alike.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Always shut off the gas or fluid supply and depressurize the line before removing or installing pipe nipples. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten to a proper engagement depth without overtightening to avoid cracking fittings. Gas line work must comply with applicable codes including the IFGC and local authority requirements.
