Bk Mueller 587-070HC Black Steel Pipe Nipple 1.5x7 Sch 40

Product Description

The BK MUELLER 587-070HC is a black steel pipe nipple designed for use in threaded pipe assemblies across gas, water, and industrial piping systems. Manufactured from welded steel with a black finish coating, it measures 1-1/2 inches in diameter and 7 inches in length, conforming to Schedule 40 wall thickness. Threads are cut to ASME B1.20.1 NPT standards, ensuring a reliable seal when assembled with compatible fittings. This nipple is a standard close-to-long connector used by plumbers, pipefitters, and mechanical contractors in both new construction and retrofit work.

This nipple is suited for residential and light commercial applications including natural gas distribution lines, black iron supply headers, steam heating systems, and general-purpose water piping where black steel is specified. Its Schedule 40 construction handles the pressure demands typical of these systems. Installers commonly use it to connect valves, tees, elbows, and other threaded fittings in gas train assemblies or mechanical room piping runs.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as applicable. Shut off all gas or water supply and relieve system pressure before disassembling or replacing any threaded pipe component. Apply approved pipe thread sealant or PTFE tape rated for the intended service to all male threads before assembly. Do not over-tighten threaded connections; use a pipe wrench with appropriate leverage for the fitting size.
