Threaded Uncoated Black Steel & Iron Pipe Fittings

2,684 products
Threaded black steel fittings connect to black steel and black iron pipe for transporting gas and water, protecting electrical wiring, or delivering high-pressure steam and air. Uncoated black steel and iron fittings, also called black malleable iron fittings, are made from corrosion-resistant ungalvanized steel with a scaly, dark-colored iron oxide coating. These fittings are used in piping systems to change direction or connect to equipment or devices. Threaded fittings twist onto pipe using various male and female thread connections including NPT (National Pipe Thread) or BSPT (British Standard Pipe Taper). Threaded fittings come in a variety of sizes and shapes.
