The black 90-degree elbow is a durable malleable iron pipe fitting designed to change the direction of water, gas, or fluid flow by 90 degrees. Available in long and short radius types, it connects directly to black iron pipes for secure and reliable installation.
MaitoLead black malleable iron fittings are widely used in fire protection systems, plumbing, natural gas and propane pipelines, and water supply networks. With excellent heat resistance, mechanical strength, and corrosion resistance, they are suitable for demanding piping applications. Standard sizes range from 1/4″ to 4″, and UL-listed and FM-approved options are available for fire protection projects.
Strict quality control and air pressure testing above 0.6 MPa ensure stable performance, helping to speed up installation and reduce overall project costs.
