USA Manufactured FNPT Black Cast Iron 11-1/4° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron 11-1/4° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron 11-1/4° Drainage Pipe Elbows provide a durable, precise solution for making very slight directional changes in commercial and industrial drain, waste, and vent piping systems. Manufactured in the United States from quality black cast iron, these specialty drainage fittings feature precision-machined female National Pipe Taper threads on both ends for joining compatible male NPT drainage pipe, nipples, adapters, and equipment outlets.

The shallow 11-1/4-degree angle allows installers to correct minor piping misalignment, create gradual offsets, or route drainage lines around structural obstructions without introducing an abrupt bend. This gentle directional change helps maintain efficient gravity flow while minimizing turbulence and unnecessary flow resistance. Precision FNPT threads support accurate alignment, secure engagement, and dependable assembly when installed with the appropriate pipe-thread sealant.

Precise Alignment for Threaded DWV Systems

Black cast iron provides excellent rigidity, dimensional stability, mechanical durability, and sound-dampening performance. USA manufactured 11-1/4° drainage elbows offer dependable dimensions and consistent thread quality for professional plumbing, mechanical, and facility-maintenance installations.

Multiple elbows may be combined when a controlled offset or larger directional change is required. Product selection and fitting placement should follow applicable plumbing codes, system design specifications, available clearance, and gravity-flow requirements.
