B K/mueller 587-045HC Black Pipe Nipple 1.5x4.5 in

Product Description

The B K/Mueller Industries 587-045HC is a black steel pipe nipple sized at 1-1/2 inches nominal diameter and 4-1/2 inches in length. Black pipe nipples are short, threaded pipe sections used to connect fittings, valves, and other components in piping assemblies. This nipple is finished in black (uncoated bare steel), making it the standard choice for gas distribution piping, compressed air lines, and general industrial or commercial plumbing systems. Plumbers, pipefitters, and gas service technicians install this type of nipple as a routine part of piping runs, manifolds, and equipment connections. The package contains 5 nipples, making it practical for jobs requiring multiple connections or service-vehicle stocking.

Black steel pipe nipples at this size are commonly found in residential and light commercial gas supply lines, boiler piping, steam systems, and compressed air distribution. The 1-1/2 inch nominal diameter suits moderate-flow branch lines and equipment connections. This nipple ships in a package of 5 units, suitable for contractors stocking a service van or completing a multi-connection installation in a single visit.

Installation Notes

Black pipe nipples are typically installed by licensed plumbers, pipefitters, or gas service technicians. Shut off all gas or system pressure and verify zero pressure at the work point before threading or unthreading any fitting. Apply an approved pipe thread sealant or PTFE tape rated for the service medium before assembly. All gas piping installations must comply with local codes and IFGC requirements, and should be pressure-tested after any modification.
