Black pipes, also called steel pipes, are used to carry water and gas from their sources to end users. Black threaded pipe is easy to work with because it can be screwed into fittings. Schedule 40 black iron pipe has thinner walls, so it is best for plumbing projects involving relatively low water pressure. We have a wide array of black pipe fittings to choose from including pipe nipples to meet your piping needs. If you’re looking for something more corrosion resistant, see our stainless steel pipe selections.
