The Grainger Black Iron Nipple (5P671) is a rugged, industrial-grade pipe fitting designed for low-pressure plumbing and mechanical applications. This Schedule 40 nipple measures 3/4" in diameter by 3" in length and features National Pipe Thread (NPT) on both ends for a secure, tapered fit into valves, elbows, or manifolds.
Commonly used in natural gas, oil, and steam lines, black iron is preferred for its high tensile strength and resistance to extreme temperatures. While it is a staple in HVAC and gas piping, it is important to note that black iron is not for use with potable (drinking) water due to its tendency to rust over time when exposed to oxygenated water.
