B K/mueller Inds(import) 586-120HN Black Steel Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 586-120HN is a black steel pipe nipple designed for threaded pipe assembly in gas, water, and industrial piping systems. Measuring 1.25 inches in diameter and 12 inches in length, this nipple provides a reliable, rigid connection between fittings in a wide range of service environments. The black finish is produced by a surface oxidation process, making it a standard choice for gas distribution piping where galvanized fittings are not permitted. Licensed plumbers, pipefitters, and gas service technicians are the primary installers of this type of fitting.

This black steel pipe nipple is suited for residential and light commercial applications including natural gas supply lines, propane distribution, and general-purpose black iron piping systems. It is commonly used in boiler rooms, mechanical rooms, and utility spaces where threaded black iron pipe systems are specified. The 12-inch length makes it appropriate for close-quarter runs that require more reach than a close or short nipple but do not require field-cut pipe. Sold in a package of 5 units.

Key Features

• Black steel construction provides corrosion resistance suitable for gas piping applications
• 1.25-inch nominal diameter with standard NPT threads for compatibility with threaded fittings
• 12-inch length suits medium-span connections without field cutting
• Sold in a package quantity of 5, reducing trip counts on multi-connection jobs
• Rigid steel body handles mechanical stress in exposed and concealed installations

Compatibility

Designed as an OEM-style replacement and standard-fit component for 1.25-inch NPT threaded black iron piping systems used in residential and commercial gas and fluid distribution applications.

Installation Notes

Installation of black steel pipe nipples in gas service must be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply and verify zero pressure before threading or disconnecting any fittings. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all threaded connections. Do not use galvanized fittings in combination with black iron in gas systems without verifying local code acceptance.
