B K Mueller 584-020HN Black Pipe Nipple 3/4 X 2 in 20 Pack

Product Description

The B K Mueller Industries 584-020HN is a black steel pipe nipple measuring 0.75 inches in diameter by 2 inches in length. Pipe nipples are short threaded pipe sections used to join fittings, valves, and equipment in piping assemblies. This nipple ships in a package of 20 units, making it practical for contractors and service techs who need multiple pieces on hand for a job. The black steel construction is standard for gas distribution piping and is a common choice in residential and light commercial mechanical systems.

This nipple is suited for use in gas supply lines, steam systems, and general black iron piping assemblies. Plumbers, pipefitters, and HVAC technicians regularly use black steel nipples when assembling or repairing gas piping runs to furnaces, boilers, water heaters, and similar appliances. The 0.75-inch diameter and 2-inch length make this a commonly specified close-work fitting for tight spaces or short offset connections.

Installation Notes

Black steel pipe nipples are typically installed by licensed plumbers or pipefitters working under applicable mechanical and gas codes such as the IFGC or local equivalents. Always shut off the gas supply and verify zero pressure at the line before disassembling or installing any gas piping component. Use an appropriate thread sealant rated for gas service on all threaded connections. Do not use black steel nipples in potable water systems where corrosion resistance is required.
