Description

  • The HVAC Premium 4" to 3" Round Sheet Metal Duct Reducer and Increaser is an essential, professional-grade ventilation fitting engineered to provide a seamless, energy-efficient transition between air ducts of different diameters.
  • Meticulously stamped from high-quality 30-gauge galvanized steel, this durable HVAC adapter utilizes a smart snap-lock seam and a corrosion-resistant coating that resists long-term moisture degradation and oxidation from heavy airflow.
  • Featuring a versatile, crimped bi-directional profile that acts as a tight inline reducer or an incremental expander, this code-compliant connector drops cleanly into position with rigid or flexible ducts, maximizing system air velocity while minimizing utility waste across bathroom exhaust, range hood, and residential heating networks.
