B K Mueller 580-030HC Black Pipe Nipple 1/8 X 3 Inch

Product Description

The B K Mueller Industries 580-030HC is a black steel pipe nipple used to create threaded connections in low-pressure piping systems. Measuring 1/8 inch in diameter and 3 inches in length, this close-cut nipple is a standard fitting in gas distribution lines, compressed air systems, and industrial piping assemblies. Plumbers, pipefitters, and gas fitters install these nipples to extend or connect pipe runs at threaded joints. The black finish indicates an uncoated steel construction suited for gas service, where galvanized fittings are typically avoided due to flaking concerns at elevated temperatures.

This nipple is used in residential and light commercial applications involving natural gas, propane, compressed air, and steam lines within pressure and temperature limits appropriate for standard black steel pipe. It is commonly installed when extending gas drops, building gas manifolds, or roughing in appliance connections. Sold in a package quantity of 10, making it practical for contractors stocking common pipe sizes for ongoing service work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or ASME B31 standards for pressure piping. Shut off and depressurize the line before threading or removing any fittings. Apply an approved thread sealant or PTFE tape rated for the service medium to all threaded joints. Pressure-test the completed assembly before returning the system to service.
