B K/mueller Inds(import) 586-001HN Black Close Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 586-001HN is a black close nipple designed for threaded pipe assemblies in gas, air, and fluid distribution systems. A close nipple is threaded along its entire length with no unthreaded center, allowing two fittings to be joined with minimal spacing between them. This 1-1/4 inch nominal size nipple is a standard component used by plumbers, pipefitters, and HVAC technicians when assembling black iron pipe systems. Its black finish is typical for gas line applications and provides a degree of corrosion resistance suited to dry service environments.

This close nipple is commonly used in residential and light commercial gas distribution piping, compressed air lines, and general industrial fluid systems where black iron pipe is specified. It is well suited for applications where fittings must be positioned as close together as possible, such as tight equipment connections, manifold assemblies, or valve installations with limited clearance. Licensed plumbers and gas fitters are the primary installers in code-governed piping systems.

Key Features

• Close-pattern threading runs the full length of the nipple for minimal installed length
• 1-1/4 inch nominal pipe size for high-flow or main-line branch connections
• Black iron finish suitable for natural gas and propane piping applications
• Packaged in a quantity of 5 per unit for efficient stocking and job-site use

Compatibility

Designed as a standard OEM-style replacement or new-installation component compatible with 1-1/4 inch NPT threaded black iron pipe fittings and valves in threaded pipe systems.

Installation Notes

Installation must be performed by a licensed plumber or qualified pipefitter in compliance with applicable local codes including the IFGC for gas service. Apply an approved thread sealant or pipe compound rated for the intended service medium before assembly. Do not overtighten, as this can crack fittings or distort threads. Shut off and depressurize the system completely before beginning any work on an existing pipe assembly.
