B K Mueller 584-025HN Black Pipe Nipple 3/4x2.5 in

Product Description

The B K Mueller Industries 584-025HN is a black steel pipe nipple measuring 3/4 inch diameter by 2-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect two fittings, valves, or other threaded components in a piping system. This nipple is manufactured in black steel, making it suitable for gas distribution lines, compressed air systems, and non-potable water applications where galvanized or brass fittings are not required. Plumbers, pipefitters, and HVAC technicians commonly install these as close connectors between valves, tees, elbows, and equipment connections.

This nipple is used in residential and light commercial piping installations. Typical applications include natural gas supply lines, propane distribution, compressed air runs, and industrial fluid transfer systems. The 3/4 inch size is a common trade size found at meter sets, appliance drops, and branch connections throughout mechanical systems. It ships in a package quantity of 15, making it practical for contractors stocking service vehicles or completing multi-connection rough-in work.

Installation Notes

Black steel pipe nipples are installed by licensed plumbers, pipefitters, or HVAC technicians following local mechanical and fuel gas codes, including the IFGC. Always shut off the gas or fluid supply and depressurize the line before making or breaking threaded connections. Apply appropriate thread sealant or PTFE tape rated for the service medium before installation. Do not over-torque threaded connections, as this can damage fittings or compromise the seal.
