1/2" Schedule 40 Black Steel Pipe Nipple

This 1/2 inch Schedule 40 black steel pipe nipple connects two female-threaded components in piping systems. It is designed for use with air, gases, non-potable water, and oils. The fitting features male NPT threads on both ends and a welded steel construction with a black finish. It suits residential, commercial, and industrial plumbing installations.

Verify Thread Size Pressure Rating

Confirm that your existing system uses 1/2 inch NPT female threads before ordering. Check that the maximum operating pressure of 300 psi at 150 degrees Fahrenheit meets your system requirements. Ensure the steel material and black coating are compatible with the specific fluids or gases being conveyed. This nipple is not rated for potable water applications.

Sustained Pressure Performance Up To 300 PSI

The Schedule 40 wall thickness supports continuous operation at the rated 300 psi pressure limit for non-steam media. For steam service, the maximum pressure rating is 150 psi at 350 degrees Fahrenheit. The electric resistance welded construction maintains structural integrity under prolonged pressurisation. The black steel finish provides standard corrosion resistance for typical plumbing environments.
