USA Manufactured FNPT Black Cast Iron Long Turn 45° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron Long Turn 45° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron Long Turn 45° Drainage Pipe Elbows provide a durable, smooth-flow solution for redirecting commercial and industrial drain, waste, and vent piping systems. Manufactured in the United States from quality black cast iron, these drainage fittings feature precision-machined female National Pipe Taper threads on both ends for secure connections with compatible male NPT drainage pipe, nipples, adapters, and equipment outlets.

The long-turn design uses an extended radius to create a gradual 45-degree directional change. Compared with a short-turn elbow, the wider sweep supports smoother gravity flow, reduces turbulence, and helps minimize areas where waste material or debris could collect. This makes the long-turn 45° drainage elbow an excellent choice for systems requiring efficient wastewater movement and improved maintenance access.

Long-Radius Cast Iron Drainage Construction

Black cast iron provides excellent rigidity, dimensional stability, mechanical durability, and sound-dampening performance. USA manufactured long-turn drainage elbows offer consistent dimensions and dependable FNPT thread quality, helping plumbing contractors and facility maintenance professionals create reliable threaded drainage assemblies.

The extended radius requires more installation space than a short-turn fitting but provides improved flow characteristics through the bend. These elbows should be selected according to applicable plumbing codes, installation clearance, system design, and gravity-flow requirements.
