Product Description
The B K/MUELLER INDS(IMPORT) 586-050HC is a black steel pipe nipple used to create threaded connections in gas, air, and liquid piping systems. Measuring 1.25 inches in diameter and 5 inches in length, this nipple threads into standard fittings on both ends to extend or join pipe runs. With a package quantity of 5 pieces per unit, it suits contractors and service techs who need multiple fittings for a job. Licensed plumbers and gas fitters install this type of nipple in residential and light commercial applications where a short, rigid threaded section is required between fittings or valves.
Black pipe nipples of this size are commonly used in natural gas and propane distribution lines, compressed air systems, and industrial fluid piping. The 1.25-inch diameter suits moderate-flow branch lines and main supply runs in residential and small commercial settings. This nipple fits standard NPT threaded fittings and valves, making it a straightforward drop-in component during new installation or repair work.
