Value Collection 43108070 Galvanized Duct Tapered Reducer

Product Description

The VALUE COLLECTION 43108070 is a galvanized steel tapered duct reducer designed to transition airflow from an 8-inch inside diameter duct down to a 7-inch inside diameter duct without a crimp end. This fitting is used in low-pressure sheet metal ductwork systems to reduce duct size while maintaining smooth, consistent airflow through the transition. The tapered profile minimizes turbulence compared to abrupt step-down fittings. At 0.82 pounds, it is lightweight and easy to handle during installation. HVAC technicians and sheet metal contractors install this type of fitting as part of supply or return air trunk-and-branch duct systems in residential and light commercial applications.

This tapered reducer without crimp is suited for residential and light commercial forced-air HVAC systems where a duct run requires a size reduction between the main trunk and a branch or terminal section. The plain end construction on both ends allows the installer to apply their own sheet metal screws and mastic or foil tape to connect to adjoining duct sections. It fits into standard galvanized round ductwork assemblies where an 8-inch-to-7-inch transition is required. No specific system or model compatibility was provided by the manufacturer for this fitting.

Key Features

• Tapered profile reduces airflow turbulence through the diameter transition
• Without-crimp end construction allows field-applied fastening and sealing
• Galvanized steel construction resists corrosion in typical HVAC duct environments
• 8-inch inlet ID to 7-inch reduced ID covers a common trunk-to-branch transition size
• 6-inch overall height keeps the fitting compact within tight duct runs
• Lightweight at 0.82 pounds for easy single-technician handling

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard round galvanized ductwork systems requiring an 8-inch to 7-inch inside diameter reduction.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors working under applicable mechanical codes such as SMACNA standards or local jurisdiction requirements. Shut down the air handling unit and confirm the system is de-energized before cutting into or modifying existing ductwork. Secure both ends of the fitting to adjoining duct sections using sheet metal screws and seal all joints with UL 181-listed mastic or foil tape to maintain duct integrity and system efficiency. Do not force-fit the reducer onto ducts of differing gauge or diameter without confirming dimensional compatibility.
