Overview

The ABB UA7HNB Schedule 40 PVC Elbow is a precision-engineered piping component designed for industrial, commercial, and electrical conduit systems requiring efficient fluid or cable direction changes. This 4-inch diameter elbow features a 45-degree bend angle and a 48-inch bend radius, optimizing flow dynamics while minimizing pressure drop in piping systems. Constructed from Schedule 40 PVC, it delivers superior chemical resistance against acids, alkalis, and corrosive substances, making it ideal for harsh environments in chemical processing, water treatment, and HVAC applications. The integral belled end design ensures secure, leak-proof solvent-weld connections with non-metallic fittings, eliminating the need for additional adapters or sealants. With a socket depth of 1.75 inches and trade size dimensions of 4.565 inches (A) at entrance and 4.465 inches (B) at bottom, this elbow meets ASTM D1784 and NEMA standards for dimensional accuracy and performance. Its 48-inch radius provides smooth directional changes, reducing turbulence and wear in high-flow systems. Key applications include underground electrical conduit runs, industrial plumbing for corrosive fluids, HVAC ductwork, and wastewater management systems. The PVC material offers a temperature range of -30°F to 140°F (-34°C to 60°C) and is UL-listed for electrical conduit use when installed per NEC guidelines. Available in single-unit packaging, the UA7HNB is manufactured by ABB Installation Products, a trusted name in industrial piping solutions. Compare this to standard 90-degree elbows: the 45-degree bend reduces installation space requirements while maintaining flow efficiency. The Schedule 40 wall thickness (0.237 inches for 4-inch pipe) ensures structural integrity under pressure up to 280 psi at 73°F, outperforming Schedule 30 alternatives in durability. For systems requiring frequent access or directional adjustments, this elbow’s design allows for easier disassembly and reassembly compared to threaded alternatives.
