B K Mueller 580-015HC Black Pipe Nipple 1/8 X 1-1/2 Inch

Product Description

The B K Mueller Industries 580-015HC is a black steel pipe nipple sized at 1/8 inch nominal diameter by 1-1/2 inches in length. Pipe nipples are short threaded pipe sections used to connect fittings, valves, and other components in a piping system. This nipple is finished in black, indicating standard carbon steel construction without galvanizing, which is the common specification for gas distribution and general industrial piping applications. Plumbers, pipefitters, and HVAC technicians routinely use close and short nipples like this one to make tight connections in low-clearance assemblies. The compact 1/8 inch size is typical in pilot gas lines, instrumentation connections, and pressure sensing taps.

This nipple is suited for residential and light commercial piping assemblies where 1/8 inch NPT connections are required. Common applications include natural gas pilot supply lines, propane distribution branches, low-pressure air lines, and steam or water instrument taps. Its small diameter makes it a frequent component in burner assemblies, gas valve piping trains, and pressure gauge installations. Sold in a package quantity of 10, this nipple is a practical stock item for service vans and shop inventory.

Installation Notes

Installation of black pipe nipples on gas lines must be performed by a licensed plumber or gas fitter in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off and lock out the gas supply before making any connections, and pressure-test the completed assembly before returning the system to service. Apply thread sealant rated for gas service to the male NPT threads; do not use standard plumber tape on gas connections unless it is specifically rated for gas. Inspect threads for damage before installation to ensure a leak-free joint.
