This duct serves as a connector between rigid ductwork, plenums, diffusers, and grilles, routing conditioned air through finished and unfinished spaces. The uninsulated construction keeps the profile lightweight and easy to route in unconditioned areas where thermal loss is managed by other means. HVAC technicians and sheet metal contractors are the primary installers for this product.\u003c\/p\u003e\u003cp\u003eThis flexible duct is suited for supply and return air applications in forced-air heating and cooling systems. Common installation scenarios include connecting air handlers to branch runs, spanning short distances between rigid trunk lines and diffusers, and fitting into tight attic or crawl space runs where rigid duct is impractical. The 50-foot length provides enough material for multiple branch drops from a single coil, reducing waste on standard residential jobs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter accommodates standard small-branch supply runs\u003c\/li\u003e\n\u003cli\u003e50-foot coil length supports multiple branch connections per roll\u003c\/li\u003e\n\u003cli\u003eUninsulated design keeps weight low and simplifies routing in conditioned or enclosed spaces\u003c\/li\u003e\n\u003cli\u003eSilver outer jacket provides a clean, finished appearance and light resistance to abrasion\u003c\/li\u003e\n\u003cli\u003eFlexible construction bends and routes around framing, joists, and obstacles without rigid fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use flexible duct for standard 4-inch residential HVAC branch supply and return applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with local mechanical codes and SMACNA flexible duct installation guidelines. Power down the air handler and confirm the system is de-energized before connecting or disconnecting any ductwork. Secure each end with an approved clamp and mastic or UL-listed foil tape rated for duct use — do not use standard cloth-backed tape. Avoid sharp bends that reduce airflow or create back-pressure in the branch run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 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: C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ATCO","offers":[{"title":"Default Title","offer_id":51306335273266,"sku":"05502504","price":25.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549387.jpg?v=1781289580","url":"https:\/\/voomisupply.com\/products\/atco-rubber-products-c-flexible-air-duct-4-in-x-50-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
