This 5-inch to 4-inch concentric duct fitting delivers a clean, reliable solution for changing diameters within a round sheet metal ventilation system. It enables precise sizing adjustments to help manage static pressure and airflow delivery in supply or exhaust runs.
Formed from high-quality 26-gauge galvanized steel, this robust reducer and increaser resists corrosion and handles the physical demands of standard HVAC systems. Its smooth inner surface helps minimize air turbulence and restriction through the transition zone.
Designed for professional contractors seeking secure, tight-fitting connections, this product facilitates easy sizing adaptations on the job site. Ensure that system dimensions, airflow velocities, and design loads align with your project requirements before installation.
