B K Mueller 587-040HN Black Steel Pipe Nipple 1.5x4 in

Product Description

The B K Mueller Industries 587-040HN is a black steel pipe nipple measuring 1.5 inches in diameter by 4 inches in length. Pipe nipples are short threaded pipe sections used to connect two female-threaded fittings or extend a run of pipe in gas, water, and mechanical systems. This nipple ships in a package of 5 units and is a standard component in residential and commercial plumbing and gas distribution rough-in work. The black finish indicates uncoated steel, making it the preferred choice for natural gas and propane distribution lines where galvanized fittings are not permitted by code.

This nipple is used in a range of trade applications including gas supply lines for furnaces, boilers, water heaters, and commercial cooking equipment. It also sees use in industrial process piping, fire sprinkler systems, and mechanical room headers. The 1.5-inch nominal pipe size is common in main distribution runs and branch feeds in both residential and light commercial construction. Licensed plumbers and pipefitters are the primary installers of this fitting.
