This type of fitting is used to connect two duct runs of different diameters, maintaining airflow continuity through the transition. It is a standard sheet metal duct component installed in residential and light commercial HVAC ductwork systems. HVAC technicians and sheet metal installers select this fitting when a duct run changes diameter, whether reducing from a larger trunk or stepping up to match a branch connection.\u003c\/p\u003e\n\u003cp\u003eThe RE087 fits into typical forced-air duct systems where transitions between round duct sizes are required. Common scenarios include connecting a main supply trunk to a smaller branch run, adapting an air handler outlet to a downstream duct section, or reconfiguring ductwork during a system replacement or renovation. This fitting is suited for both new construction and retrofit installations where a clean, secure 8-to-7 inch round duct transition is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 8-inch and 7-inch round duct diameters\u003c\/li\u003e\n  \u003cli\u003eStandard reducer-increaser profile for low-resistance airflow transition\u003c\/li\u003e\n  \u003cli\u003eCompatible with round duct fittings and connections standard to the trade\u003c\/li\u003e\n  \u003cli\u003eSuitable for supply and return air duct applications in forced-air systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for 8-inch to 7-inch round duct systems in residential and light commercial forced-air HVAC installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or sheet metal installer in accordance with local mechanical codes and SMACNA duct construction standards. Power the air handling unit off before working inside an active duct system. Secure the fitting with sheet metal screws and seal all joints with listed duct sealant or UL 181-rated foil tape to prevent air leakage. Do not leave unsealed joints in conditioned or pressurized duct sections.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Reducer-Increaser\u003c\/li\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: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Shape\u003c\/strong\u003e: Round\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: RE087\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51343547236658,"sku":"RE087","price":22.21,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553370.jpg?v=1782022591","url":"https:\/\/voomisupply.com\/products\/air-flow-products-re087-reducer-increaser-8-to-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
