Based on the part designation, this fitting connects a 7-inch duct section to a 5-inch duct section, allowing airflow to pass through a diameter change without the need for field fabrication. It is a standard sheet metal fitting installed by HVAC technicians and sheet metal workers during new construction or duct modification work.\u003c\/p\u003e\n\u003cp\u003eThis type of reducer-increaser fitting is used in residential and light commercial duct systems where a trunk line or branch run changes diameter. It is suited for supply or return air applications where a smooth transition between duct sizes is required to maintain airflow efficiency. Installers use this fitting when downsizing or upsizing duct runs at junction points, air handler connections, or branch takeoffs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 7-inch and 5-inch round duct diameters\u003c\/li\u003e\n  \u003cli\u003eReducer-increaser design allows use in both downsizing and upsizing configurations\u003c\/li\u003e\n  \u003cli\u003eStandard round duct fitting for straightforward integration into existing duct systems\u003c\/li\u003e\n  \u003cli\u003eEliminates the need for field-fabricated transitions at diameter change points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 7-inch to 5-inch round duct systems in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal workers. Turn off the air handling unit or furnace before disconnecting or modifying any duct sections. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant per local mechanical code requirements. Do not overtighten screws on thin-gauge fittings, as this can distort the collar and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Round Duct Reducer-Increaser\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: AIR FLOW PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RE075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51346548916530,"sku":"RE075","price":19.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553364.jpg?v=1782083508","url":"https:\/\/voomisupply.com\/products\/air-flow-products-re075-reducer-increaser-7-to-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
