This 7″x6″ tapered duct reducer is designed to provide a smooth transition from 7-inch round duct to 6-inch round duct for HVAC supply, return, ventilation, or exhaust applications.
Made from durable galvanized steel, this reducer offers corrosion resistance and long-term reliability in residential and commercial ductwork systems.
This model is labeled NO CRIMP, meaning the ends are straight for installers who prefer custom fastening using sheet metal screws, clamps, duct sealant, or HVAC foil tape.
The tapered design improves airflow efficiency by reducing turbulence and static pressure loss compared to straight reducers.
