Description

The B K Mueller Industries 584-050HN is a black steel pipe nipple sized at 3/4 inch diameter by 5 inches in length. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and other components in a piping system. This nipple features male NPT threads on both ends, allowing for straightforward installation into tees, elbows, couplings, and valves. The black finish is standard for non-galvanized steel pipe and is commonly specified for gas distribution and general-purpose piping in commercial and residential applications. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers of this fitting.

This black pipe nipple is suited for use in natural gas, propane, and general-purpose low-pressure piping systems where galvanized fittings are not required or are prohibited. It is commonly installed in residential and light commercial gas supply lines, boiler rooms, mechanical rooms, and similar utility piping runs. Sold in packages of 20 units, making it practical for service vans and job-site stock. Applications include connecting gas valves, manifolds, drip legs, and union assemblies in standard pipe configurations.
