This fitting steps down from a 6-inch connection to a 5-inch connection using a smooth tapered profile, which helps maintain airflow velocity and reduces turbulence at the transition point. At 0.4 pounds, it is lightweight and easy to handle during installation. HVAC sheet metal technicians and mechanical contractors use this fitting when resizing duct runs, connecting trunks to branch lines, or adapting existing ductwork to new equipment connections.\u003c\/p\u003e\n\u003cp\u003eThis tapered reducer is part of the MM MANUFACTURING 400 series, which is available in 42 size combinations ranging from 4 inches x 3 inches up to 24 inches x 22 inches. The 400-6X5 is suited for residential and light commercial forced-air systems where a 6-inch to 5-inch round duct transition is required. It fits into standard sheet metal duct assemblies and is appropriate for supply or return air applications where a smooth diameter reduction is needed along a duct run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTapered profile transitions from 6 inches to 5 inches for smooth airflow reduction\u003c\/li\u003e\n  \u003cli\u003ePart of a 42-size combination product series covering 4 inches x 3 inches through 24 inches x 22 inches\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.4 pounds for easy single-technician handling\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 6 inches length x 6 inches width x 6.75 inches height\u003c\/li\u003e\n  \u003cli\u003eDesigned for round duct transitions in forced-air HVAC supply and return systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sheet metal tapered reducer for standard round duct systems requiring a 6-inch to 5-inch diameter transition in residential or light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with local mechanical codes and SMACNA ductwork standards. Power down the air handling unit and confirm the system is de-energized before working in the duct. Secure the fitting with sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant to prevent air leakage. Do not force the fitting onto connections of a different diameter than specified.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 400-6X5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M\u0026M MANUFACTURING","offers":[{"title":"Default Title","offer_id":51268905861426,"sku":"400-6X5","price":18.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913442.webp?v=1780709348","url":"https:\/\/voomisupply.com\/products\/mm-manufacturing-400-6x5-tapered-reducer-6x5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
