B K Mueller 585-025HN Black Steel Pipe Nipple 1x2.5 in

Product Description

The B K Mueller Industries 585-025HN is a black steel pipe nipple sized at 1 inch by 2.5 inches. Pipe nipples are short threaded sections of pipe used to connect two fittings, valves, or other piping components within a system. This nipple is finished in black, indicating it is made from black steel rather than galvanized material, making it suitable for gas distribution, fire suppression, and general plumbing applications. It ships in a package quantity of 10 units. Licensed plumbers, pipefitters, and gas service technicians install these as part of standard pipe assemblies.

Black steel pipe nipples of this size see wide use in residential and light commercial applications. Common install scenarios include natural gas and propane distribution lines, steam heating systems, and industrial process piping where galvanized coatings are not required or not permitted. The 1-inch diameter and 2.5-inch length make this nipple appropriate for tight-clearance connections in mechanical rooms, utility spaces, and equipment stub-outs. It is sold in a package of 10, making it practical for service trucks and job-site inventory.

Installation Notes

Installation of black steel pipe nipples on gas lines must comply with IFGC requirements and all applicable local codes, and should be performed by a licensed plumber or gas fitter. Shut off gas supply and verify the line is fully depressurized before disassembling any threaded connections. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all threaded joints. Do not use black steel nipples in systems where galvanized or stainless material is specifically required.
