B K Mueller 587-030HN Black Pipe Nipple 1.5x3 in 5-pack

Product Description

The B K Mueller Industries 587-030HN is a black steel pipe nipple measuring 1.5 inches in 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 finished in black, indicating a non-galvanized steel construction common in gas distribution, steam, and general industrial piping systems. Licensed plumbers, pipefitters, and gas service technicians install nipples of this type as part of new construction, system extensions, or repairs. This package contains 5 nipples per unit of measure.

The 587-030HN is suited for residential and light commercial plumbing, heating, and gas piping applications where a short close-nipple or fixed-length connector is required between threaded components. Black steel nipples are frequently used in natural gas and propane supply lines, steam heating systems, and industrial fluid distribution where galvanized coatings are not permitted or preferred. Install in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) as the application requires.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified gas technician in accordance with local codes and IFGC or IPC requirements. Shut off gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
