This fitting steps down from a 7-inch inlet to a 6-inch outlet using a smooth tapered profile that reduces turbulence and pressure drop at the transition point. Weighing 0.45 pounds, it is a lightweight, easy-to-handle fitting suited for new construction ductwork runs, equipment changeouts, and service repairs. HVAC installers and sheet metal contractors use this type of fitting wherever a trunk-to-branch or equipment-to-duct diameter change is required.\u003c\/p\u003e\n\u003cp\u003eThis reducer is part of the MM MANUFACTURING 400 series, which covers 42 size combinations ranging from 4 inches x 3 inches up to 24 inches x 22 inches. The 400-7X6 fits residential and light commercial forced-air applications where a 7-inch-to-6-inch round duct transition is needed. It is commonly installed on supply or return ductwork trunks, air handler collars, and inline duct runs where airflow must be stepped down to match downstream branch sizing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered profile reduces turbulence at the diameter transition compared to abrupt step reducers\u003c\/li\u003e\n  \u003cli\u003e7-inch inlet to 6-inch outlet configuration for common residential duct sizing\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.45 pounds for easy single-technician handling and installation\u003c\/li\u003e\n  \u003cli\u003ePart of a 42-size series allowing consistent fitting selection across a wide range of duct diameters\u003c\/li\u003e\n  \u003cli\u003eOverall dimensions of 7 inches length x 7 inches width x 6.5 inches height\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 7-inch to 6-inch tapered reduction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is typically installed by licensed HVAC technicians or sheet metal contractors working on forced-air duct systems. Power down the air handling unit or furnace at the disconnect before modifying any ductwork. Secure the fitting with sheet metal screws and seal all joints with listed duct sealant or UL 181-rated tape per applicable mechanical codes. Do not rely on friction fit alone in pressurized duct runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.45 pounds\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: MM MANUFACTURING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 400-7X6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M\u0026M MANUFACTURING","offers":[{"title":"Default Title","offer_id":51268015980850,"sku":"400-7X6","price":18.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913443.webp?v=1780697026","url":"https:\/\/voomisupply.com\/products\/mm-manufacturing-400-7x6-tapered-reducer-7x6-duct-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
