Spiral Duct Wye Fittings — 3" to 20"

Yes. In addition to standard spiral duct wye fittings, Duct Incorporated offers custom fabrication for non-standard sizes or configurations. Custom fabrication is ideal when standard fittings do not match your system layout or when unique branch angles are required for your design.

Spiral duct wye fittings are commonly used in industrial dust collection systems, HVAC ductwork installations, material handling and pneumatic conveying systems, and general industrial ventilation. They enable airflow to be split or branched efficiently from a main duct run to secondary runs.

Wye fittings branch airflow at an angled split, typically 30° to 45°, which reduces turbulence and pressure drop compared to standard tee fittings. This makes wye fittings preferable in systems where maintaining airflow velocity and minimizing resistance are critical, such as dust collection and pneumatic conveying.

Spiral duct wye fittings are most commonly fabricated from galvanized steel, which provides durability and corrosion resistance for standard HVAC and ventilation applications. Specialty materials may be available through custom fabrication for applications involving corrosive materials, high temperatures, or specific regulatory requirements.
