B K Mueller 587-025HC Black Steel Pipe Nipple 1.5x2.5in 5pk

Product Description

The B K Mueller Industries 587-025HC is a black steel pipe nipple used to connect threaded pipe sections in plumbing, gas distribution, and mechanical piping systems. This close-pattern nipple measures 1.5 inches in diameter by 2.5 inches in length and ships in a package of 5 units. Black steel pipe nipples are a standard fitting in gas line installations, fire suppression roughing, and general industrial piping. Licensed plumbers and pipefitters install these as part of threaded black iron piping assemblies in both residential and commercial applications.

This nipple is suited for low-pressure gas piping, steam, air, and water systems where black steel pipe fittings are specified. The 1.5-inch nominal size is common in branch lines, boiler connections, unit heater feeds, and similar mechanical piping runs. The 2.5-inch threaded length makes it appropriate for close-quarter connections where a longer run of pipe is not needed. This package contains 5 nipples, making it practical for multi-connection jobs or service stock.

Compatibility

Designed as a standard NPT-threaded black steel pipe nipple for use in 1.5-inch nominal threaded piping systems, including gas distribution, steam, air, and water lines in residential and commercial mechanical applications.

Installation Notes

Black steel pipe nipples are installed by licensed plumbers or pipefitters working on gas, steam, or mechanical piping systems. Shut off and depressurize the line before disassembly or installation. Apply an approved pipe thread sealant or PTFE tape rated for the specific service fluid before threading. All gas piping work must comply with applicable local codes and the International Fuel Gas Code (IFGC).
