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

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

USA Manufactured FNPT Black Cast Iron Long Turn 90° Drainage Pipe Elbows provide a durable, smooth-flow solution for changing the direction of drain, waste, and vent piping. Manufactured in the United States from quality black cast iron, these industrial drainage fittings feature precision-machined female National Pipe Taper connections for joining compatible male NPT drainage pipe, nipples, adapters, and equipment outlets.

The long-turn 90-degree pattern uses a wider radius than a standard or short-turn elbow. This gradual directional change helps improve gravity flow, reduce turbulence, and limit the buildup of waste or debris inside the piping system. The extended sweep can also make drain cleaning and maintenance easier by allowing equipment to pass through the bend more smoothly.

Smooth Flow for Gravity Drainage Systems

Black cast iron provides excellent rigidity, dimensional stability, mechanical durability, and natural sound-dampening performance. USA manufactured black cast iron long-turn drainage elbows help reduce the transmission of wastewater noise through walls, ceilings, mechanical rooms, and occupied commercial spaces.

Precision-machined FNPT threads promote accurate engagement and dependable alignment when installed with a suitable pipe-thread sealant. These fittings are generally intended for non-pressure drainage applications. Installers should confirm nominal pipe size, available space, flow direction, code requirements, and system compatibility before installation.
