Black pipe fittings from Grainger can be used to make connections to black iron and black steel pipe commonly used for transporting gas and water. Black fittings, which are actually black malleable iron fittings, can form a tighter seal than black steel fittings because they are more flexible. You'll find both types here, as well as galvanized steel and cast iron fittings. Choose from street elbows, couplings, crosses, caps, tees and more in a wide range of pipe sizes. Shop Grainger today to find the black pipe fittings you need.
