Built with a 12-inch diameter and an R-4.2 insulation rating, this flex duct handles main supply runs where moderate thermal performance and routing flexibility are both required. Its construction allows installation in tight underfloor spaces and confined pathways typical of mobile and manufactured home construction. HVAC technicians and installers working in the manufactured housing segment rely on this product for dependable airflow distribution within constrained duct routing environments.\u003c\/p\u003e\n\u003cp\u003eThis flex duct is intended for use in manufactured and mobile home HVAC systems, primarily on main supply trunk runs where a 12-inch diameter provides adequate airflow capacity. The flexible design accommodates the angled and curved routing common under mobile home platforms. It is suited for residential manufactured housing installations where system design calls for moderate insulation performance and installation ease in underfloor cavities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-inch diameter sized for main supply distribution runs in mobile home HVAC systems\u003c\/li\u003e\n  \u003cli\u003eR-4.2 insulation rating delivers moderate thermal performance for underfloor environments\u003c\/li\u003e\n  \u003cli\u003eFlexible construction allows routing around obstructions in confined underfloor spaces\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for manufactured and mobile home HVAC applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation flex duct for residential manufactured and mobile home HVAC air distribution systems requiring a 12-inch diameter supply duct.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician familiar with manufactured housing duct systems. Power down the HVAC unit and verify the system is off before connecting or repositioning any duct sections. Support the duct at regular intervals to prevent sagging, which reduces airflow efficiency. Seal all connections with approved mastic or metal-backed tape in accordance with applicable mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-4.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Manufactured and mobile home HVAC air distribution\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: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12MD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51344333209906,"sku":"12MD","price":105.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552753.jpg?v=1782033480","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-12md-mobile-home-flex-duct-r-4-2","provider":"Voomi Supply","version":"1.0","type":"link"}
