This silver-jacketed duct provides a flexible, low-resistance airflow path between supply plenums, branch takeoffs, and diffusers or registers. Its uninsulated construction makes it appropriate for conditioned-space runs where condensation and thermal loss are not primary concerns. HVAC installers and sheet metal contractors work with this duct type on new construction and retrofit projects requiring a compact, flexible run in tight or irregular framing cavities.\u003c\/p\u003e\u003cp\u003eThis duct is suited for supply-side air distribution in residential forced-air systems and light commercial applications where a 3-inch round duct is specified. Common install scenarios include bathroom exhaust, small branch supply runs, and rangehood or ventilation connections where short to medium runs are needed and insulation is not required by the system design or local mechanical code. Always verify local code requirements before selecting uninsulated duct for a given application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch inner diameter for compact branch supply and ventilation runs\u003c\/li\u003e\n\u003cli\u003e50-foot length provides adequate material for multiple branch connections per roll\u003c\/li\u003e\n\u003cli\u003eFlexible construction allows routing around framing, joists, and obstructions without rigid fittings\u003c\/li\u003e\n\u003cli\u003eUninsulated design reduces cost and weight for conditioned-space or short interior runs\u003c\/li\u003e\n\u003cli\u003eSilver jacket finish is compatible with standard HVAC duct tape and mastic sealants\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flexible duct replacement or new-installation material compatible with standard 3-inch round HVAC fittings, collars, and takeoffs used in residential and light commercial forced-air distribution systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified mechanical contractor in accordance with local mechanical codes and SMACNA flexible duct installation standards. Power down the air handling unit and close the system dampers before making connections. Secure both ends of the duct to collars or takeoffs using approved mechanical fasteners and seal all joints with UL 181-rated mastic or foil tape. Avoid sharp bends, kinks, or excessive compression, as these reduce airflow and system efficiency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: Uninsulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Color\u003c\/strong\u003e: Silver\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ATCO RUBBER PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5502503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATCO","offers":[{"title":"Default Title","offer_id":51306770071858,"sku":"05502503","price":23.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549550.jpg?v=1781297999","url":"https:\/\/voomisupply.com\/products\/atco-rubber-products-5502503-flexible-air-duct-3in-x-50ft","provider":"Voomi Supply","version":"1.0","type":"link"}
