USA Manufactured FNPT Black Cast Iron 22-1/2° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron 22-1/2° Drainage Pipe Elbow

USA Manufactured FNPT Black Cast Iron 22-1/2° Drainage Pipe Elbows provide a durable, gradual solution for making minor directional changes in 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 connecting compatible male NPT drainage pipe, nipples, adapters, and equipment outlets.

The 22-1/2-degree angle creates a gentle offset that is less abrupt than standard 45-degree or 90-degree drainage elbows. This gradual change helps installers align piping, avoid structural obstructions, and correct minor routing differences without creating an unnecessarily sharp bend. Precision FNPT threads promote accurate alignment, dependable engagement, and a secure connection when installed with an appropriate pipe-thread sealant.

Gradual Directional Change for DWV Systems

Black cast iron offers excellent rigidity, dimensional stability, mechanical durability, and sound-dampening performance. USA manufactured 22-1/2° drainage elbows provide consistent dimensions and dependable thread quality for professional plumbing and mechanical installations.

The shallow-angle design can help maintain efficient gravity flow while reducing turbulence and flow resistance through the fitting. Two 22-1/2° elbows may also be used to create a controlled 45-degree offset when additional routing flexibility is required. Fitting selection should follow applicable plumbing codes, system design, and installation requirements.
