Air Flow Products RE076 Reducer Increaser 7 to 6 in

Product Description

The AIR FLOW PRODUCTS RE076 is a reducer-increaser duct fitting designed to transition between two different duct diameters in forced-air HVAC systems. This fitting connects a 7-inch duct section to a 6-inch duct section, allowing installers to reduce or increase airflow path size as needed within a duct run. It is a standard component used during new duct system construction and retrofit work where trunk-to-branch transitions or size changes are required. Licensed HVAC technicians and sheet metal contractors are the primary installers of this type of fitting.

The RE076 is suited for residential and light commercial forced-air applications where duct diameter changes are needed along a supply or return air trunk. Common installation scenarios include connecting a larger trunk line to a smaller branch run, or adapting existing ductwork to new equipment with different collar sizes. This fitting is appropriate for use in both new construction and service replacement situations.

Key Features

• Transitions between 7-inch and 6-inch round duct diameters
• Designed for use in forced-air supply or return duct systems
• Standard reducer-increaser geometry for smooth airflow transition
• Suitable for residential and light commercial HVAC duct installations

Compatibility

Designed as an OEM-style replacement and standard fitting for round duct systems requiring a 7-inch to 6-inch diameter transition in residential or light commercial forced-air installations.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with applicable mechanical codes. Power down the air handling equipment before working on the duct system. Secure the fitting to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to prevent air leakage. Verify airflow direction and fitting orientation before final fastening.
