B K/mueller Inds(import) 588-100HC Black Pipe Nipple

Product Description

The B K/MUELLER INDS(IMPORT) 588-100HC is a black steel pipe nipple measuring 2 inches in diameter and 10 inches in length. Pipe nipples are short sections of threaded pipe used to connect fittings, valves, and other piping components in gas, air, and fluid distribution systems. This nipple features a black finish, which is standard for gas piping applications, and is sold in a package of 5 units. Licensed plumbers, pipefitters, and gas technicians rely on nipples like this one to complete pipe runs, extend lines, and connect branch fittings in both residential and commercial installations.

This black pipe nipple is suited for use in natural gas, propane, compressed air, and general plumbing piping systems where black iron or black steel pipe and fittings are specified. Common installation scenarios include gas supply lines to appliances such as furnaces, boilers, water heaters, and commercial cooking equipment, as well as compressed air distribution in shop and industrial environments. The 2-inch diameter makes this nipple appropriate for medium-to-large capacity supply lines in light commercial and residential applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable local codes, IFGC requirements for gas systems, and ASME B31 piping standards where applicable. Always shut off the gas or fluid supply and depressurize the line before removing or installing pipe nipples. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium to all threaded connections before assembly. Do not over-tighten threaded connections, as this can damage threads or crack fittings.
