Bk Mueller 586-240HC Black Pipe Nipple 1-1/4 in X 24 in Sch 40

Product Description

The BK MUELLER 586-240HC is a Schedule 40 black steel pipe nipple designed for use in gas, air, and fluid distribution systems where a threaded, close-run connection is required. Measuring 1-1/4 inches in diameter and 24 inches in length, this nipple is welded construction with a black finish coating and NPT threads on both ends conforming to ASME B1.20.1. It meets ASTM A733 standards for welded steel pipe nipples. At 9.5 pounds, it is sized for commercial and residential installations where heavier-wall, full-length nipples are needed. Plumbers and pipefitters install this part in gas distribution, compressed air lines, and general-purpose pipe runs.

This nipple is a standard fit for Schedule 40 black steel piping systems in residential and light commercial applications. Typical uses include natural gas and propane distribution piping, steam systems, and industrial fluid lines where steel pipe and threaded fittings are specified. The 24-inch length makes it suitable as a full-length nipple in branch runs, riser assemblies, or equipment connections. It mates with standard Schedule 40 black malleable iron or steel fittings and valves using 1-1/4-inch NPT threaded ends.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable codes including the IFGC and IPC. Shut off and depressurize the line completely before removing or installing any threaded nipple. Apply an approved thread sealant or PTFE tape to the male threads before makeup, and tighten using properly sized pipe wrenches. Do not over-tighten or use impact tools, as this can damage the thread form or fitting body.
