This type of fitting is used to step duct size up or down along a supply or return air run, maintaining airflow continuity through the system. It carries a series designation of 85, indicating its fitting profile within the AIR FLOW PRODUCTS lineup. HVAC installers and sheet metal mechanics use fittings like the RE108 when connecting trunks, branches, or equipment collars that differ in diameter.\u003c\/p\u003e\n\u003cp\u003eThe RE108 is suited for residential and light commercial ductwork installations where a 10-inch to 8-inch round duct transition is required. Typical applications include connecting a larger trunk line to a smaller branch run, reducing down from a plenum outlet, or stepping up from equipment connections to larger duct runs. The fitting works within standard round duct systems using conventional slip or drive connections common to sheet metal ductwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions between 10-inch and 8-inch round duct diameters\u003c\/li\u003e\n  \u003cli\u003eSeries 85 fitting profile for standard duct system integration\u003c\/li\u003e\n  \u003cli\u003eFunctions as both a reducer and increaser depending on airflow direction\u003c\/li\u003e\n  \u003cli\u003eCompatible with conventional round duct slip and drive connection methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for residential and light commercial round duct systems requiring a 10-inch to 8-inch diameter transition.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of duct fittings should be performed by a licensed HVAC technician or qualified sheet metal mechanic in accordance with applicable mechanical codes, including SMACNA ductwork standards. Power down the air handling unit or furnace at the disconnect before opening the duct system. Seal all joints with listed duct sealant or metal-backed tape per local code requirements. Do not use standard cloth duct tape as a primary air 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: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 85\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: RE108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AIR FLOW PRODUCTS","offers":[{"title":"Default Title","offer_id":51343235252530,"sku":"RE108","price":24.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553292.jpg?v=1782019640","url":"https:\/\/voomisupply.com\/products\/air-flow-products-re108-reducer-increaser-10-to-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
