Vent Wye 4" x 4" x 4"

The 4-inch Vent Wye is an essential component for any HVAC or ventilation system. Engineered to create a smooth airflow split (or merge) between three ducts, its angled design minimizes turbulence and pressure loss. Whether you’re installing a new HVAC run, extending existing ductwork, or repairing a damaged tee, this Vent Wye provides reliable performance in residential, commercial, and light‐industrial applications.

Constructed for easy installation, the uniform 4″ branches fit standard duct connectors and are compatible with sheet metal, flex, and insulated duct systems. Its sturdy design helps maintain optimal airflow while reducing noise and energy waste throughout your ventilation network.
