Black Pipe Fittings

Black iron is one of the toughest materials available and black iron pipe fittings are often used in natural gas piping as they can withstand the pressure associated with gas lines. Black iron pipe fittings are also used in plumbing and HVAC applications in homes and commercial buildings. Malleable black iron fittings are hardened to ensure they can handle extreme pressure of twisting into parts into place. Shop with us for black iron pipe fittings and malleable fittings in several sizes and shapes including elbow, tees, couplings, unions plugs (caps).
