It steps an 8-inch duct down to a 6-inch duct — or increases from 6 inches to 8 inches — using a smooth taper profile without a crimped end. Fabricated from 28-gauge galvanized steel, this fitting delivers solid corrosion resistance and structural rigidity appropriate for low-pressure supply and return air applications. HVAC installers and sheet metal mechanics use this fitting to connect duct sections of differing diameters without improvising transitions on the job.\u003c\/p\u003e\n\u003cp\u003eThis reducer\/increaser is suited for forced-air heating and cooling duct systems where a direct size change between 8-inch and 6-inch round duct is required. The no-crimp design allows either end to accept standard duct collars, snap-lock fittings, or drive cleats depending on the installation method. Typical applications include branch takeoffs, trunk-to-branch transitions, and equipment connections in residential new construction and retrofit ductwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 8-inch and 6-inch round duct in either direction\u003c\/li\u003e\n  \u003cli\u003eNo-crimp ends allow flexible connection to standard fittings on both sides\u003c\/li\u003e\n  \u003cli\u003e28-gauge galvanized steel construction provides corrosion resistance for long-term duct service\u003c\/li\u003e\n  \u003cli\u003eSmooth taper profile minimizes airflow turbulence at the transition point\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 10 units, suitable for contractor stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit component for 8-inch and 6-inch round galvanized duct systems in residential and light commercial forced-air HVAC installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handling system before making duct connections. Secure both ends with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with local mechanical codes. Do not over-compress the fitting during installation, as deformation of the taper can restrict airflow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 28 GA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: No Crimp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IMPERIAL MFG GROUP USA INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GV0791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":51557928960306,"sku":"GV0791","price":151.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3e8498b1784b47b0c2d13723e948a5dc_362148ba-a93a-458d-852c-6a8a85657f63.jpg?v=1786398663","url":"https:\/\/voomisupply.com\/products\/imperial-mfg-group-usa-inc-gv0791-taper-reducer-8x6-28ga","provider":"Voomi Supply","version":"1.0","type":"link"}
