B K Mueller 584-030HN Black Steel Pipe Nipple 3/4x3

Product Description

The B K Mueller Industries 584-030HN is a black steel pipe nipple sized at 0.75 inches nominal diameter by 3 inches in length. Pipe nipples are short threaded fittings used to connect two female-threaded pipe fittings, valves, or equipment ports. This nipple is manufactured from black steel, making it a standard choice for gas distribution, compressed air, and non-potable water piping systems. Licensed plumbers, gas fitters, and pipefitters install these fittings in both residential and light commercial applications. The black finish is characteristic of uncoated steel used in dry or gas-service piping. Each unit is sold individually and ships in packages of 15.

This pipe nipple is suited for threaded piping assemblies in residential and commercial settings. Common applications include natural gas and propane supply lines, steam piping, compressed air distribution, and industrial process piping where black steel is the specified material. It is not intended for potable water service. The 0.75-inch nominal thread size fits standard NPT-threaded fittings, valves, and manifolds of the same size.

Key Features

• 0.75-inch nominal diameter x 3-inch length for short-reach threaded connections
• Black steel construction suitable for gas, steam, and compressed air service
• Standard NPT threads for compatibility with threaded fittings and valves

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the service type. Always shut off gas supply or depressurize the line before removing or installing threaded fittings. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all threads before assembly. Do not use black steel nipples in potable water service.
