USA Manufactured FNPT Black Cast Iron Extra Long Turn 90° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron Extra Long Turn 90° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron Extra Long Turn 90° Drainage Pipe Elbows provide a smooth, gradual directional change for commercial and industrial drain, waste, and vent piping systems. Manufactured in the United States from durable black cast iron, these 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 extra-long-turn design provides a wider sweeping radius than standard long-turn or short-turn drainage elbows. This extended curve helps maintain efficient gravity flow through the 90-degree bend while reducing turbulence, flow resistance, and the potential for waste materials to collect inside the fitting. The design is especially valuable for drainage systems carrying solids or requiring improved cleanout accessibility.

Extra-Long Sweep for Improved Drainage Flow

Black cast iron provides excellent rigidity, dimensional stability, durability, and sound-dampening performance. USA manufactured extra-long-turn drainage elbows offer consistent dimensions and dependable FNPT thread quality for professional plumbing and mechanical installations.

Because the extra-long sweep requires additional installation space, system layouts should allow sufficient clearance around walls, floors, structural supports, and nearby equipment. These fittings are intended for gravity-flow drainage service rather than pressurized air, gas, steam, or process piping.
