B K Mueller 584-100HN Black Steel Pipe Nipple 0.75x10 in

Product Description

The B K Mueller Industries 584-100HN is a black steel pipe nipple designed for use in threaded pipe assemblies across residential and light commercial plumbing, gas distribution, and mechanical piping systems. Measuring 0.75 inches in diameter and 10 inches in length, this close-cut nipple provides a reliable threaded connection between fittings, valves, and other piped components. Licensed plumbers, pipefitters, and gas technicians rely on black steel nipples for natural gas, propane, and other non-corrosive media applications where galvanized or copper pipe is not specified. This SKU ships as a package of 10 pieces.

Black steel pipe nipples of this type are commonly used in residential gas supply lines, boiler piping, steam systems, and industrial process piping. The 0.75-inch nominal diameter and 10-inch length make this nipple suitable for branch connections, riser extensions, and equipment drops. It is installed wherever a short, rigid threaded section is needed between two female-threaded fittings or valves. The package quantity of 10 supports stocking needs for service vehicles or shop inventory.

Installation Notes

Black steel pipe nipples are installed by licensed plumbers or pipefitters in accordance with IFGC and applicable local mechanical codes. Shut off and purge any gas or fluid supply before disconnecting existing piping. Apply an approved thread sealant or PTFE tape rated for the intended media before making up threaded joints. Do not over-torque threaded connections, as this can crack fittings or distort threads.
