B K/mueller Inds(import) 586-020HN Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 586-020HN is a black steel pipe nipple measuring 1-1/4 inches in diameter and 2 inches in length. This short-length threaded fitting is used to connect two female-threaded fittings, valves, or pipe sections in low-pressure piping systems. The black finish is standard for gas and non-potable piping applications. It weighs approximately 1.34 pounds and is sold in a package of 5. Licensed plumbers and pipefitters commonly install this type of nipple in residential and light commercial systems.

This nipple is suited for use in gas distribution, heating, and general-purpose piping systems where black iron or black steel fittings are required. The 1-1/4 inch nominal pipe size and 2 inch body length make it a common choice for close-coupled connections between valves, tees, unions, and other threaded components. It is appropriate for above-grade, exposed, or concealed indoor piping where the system requires a short threaded extension.

Installation Notes

Black pipe nipples are typically installed by licensed plumbers or pipefitters following local plumbing and mechanical codes, including applicable sections of the IFGC for gas piping applications. Shut off gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant or PTFE tape rated for the service type before making up connections. Do not overtighten threaded joints, as this can crack fittings or damage threads.
