Value Collection NB08040 Black Steel Pipe Nipple 1.5x4 Sch 40

Product Description

The VALUE COLLECTION NB08040 is a Schedule 40 black steel pipe nipple used to connect threaded pipe sections in plumbing, mechanical, and industrial piping systems. It measures 1-1/2 inches in diameter and 4 inches in length, with 1-1/2-inch NPT threads on both ends conforming to ANSI B1.20.1 and ASME B1.20.1 standards. The black finish results from a mill-applied iron oxide coating. This nipple is installed by licensed plumbers, pipefitters, and mechanical contractors in a wide range of fluid and gas distribution applications.

This nipple suits residential and commercial piping installations where short close-to-fitting connections are required. Common applications include natural gas distribution lines, steam systems, compressed air headers, and general water supply piping. The Schedule 40 wall thickness is appropriate for standard service pressures encountered in most residential and light commercial mechanical systems. It threads directly into Schedule 40 and Schedule 80 black iron fittings, tees, elbows, and valves.

Installation Notes

Installation is performed by licensed plumbers or pipefitters. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, following local plumbing and mechanical codes such as the IPC or IFGC. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
