B K Mueller 587-020HN Black Pipe Nipple 1.5x2 in

Product Description

The B K Mueller Industries 587-020HN is a black steel pipe nipple sized at 1.5 inches by 2 inches, used to create short threaded connections in piping systems. Black pipe nipples serve as close connectors between fittings, valves, and other threaded components in gas, steam, and general plumbing distribution lines. This nipple is sold in a package of 5 pieces, making it well suited for jobs requiring multiple connections. Licensed plumbers, pipefitters, and gas technicians regularly specify black pipe nipples for low-pressure gas distribution and industrial fluid conveyance where galvanized fittings are not required.

This nipple is intended for use in residential and light commercial piping systems. Common applications include natural gas and propane supply lines, steam heating distribution, and industrial air or fluid lines. The 1.5-inch by 2-inch dimensions suit short-run connections between threaded fittings such as tees, elbows, and valves. It is not intended for potable water service due to the black steel finish.

Key Features

• 1.5-inch nominal pipe size with a 2-inch overall length for short-run connections
• Black steel construction suitable for gas, steam, and non-potable fluid service
• Threaded ends for standard NPT fitting connections
• Sold in a package of 5 pieces per unit of measure

Compatibility

Designed as a standard NPT-threaded replacement or new-installation nipple for 1.5-inch black steel piping systems used in gas distribution, steam heating, and general industrial piping applications.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or gas technicians in accordance with applicable codes such as the IFGC or ANSI standards for gas piping. Before any work, shut off the gas supply or fluid source at the isolation valve and verify pressure has been relieved. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to the male threads before making up the connection. Do not use black pipe nipples on potable water systems.
