A 1-1/4 in. x 10 ft. black iron pipe (black steel pipe) is a Schedule 40 steel pipe commonly used for gas, air, oil, and non-potable water systems. It typically comes threaded on both ends (NPT) for easy connection to fittings.

Black steel pipe is widely used in residential and commercial plumbing because it can handle high pressure, high temperatures, and gas applications.
