This product is part of the HC F216 series and measures 8 inches in diameter by 25 feet in length. It delivers reliable airflow from air handlers, furnaces, and ductwork systems to supply registers and diffusers throughout a structure. HVAC technicians and sheet metal contractors rely on flexible duct like this for its ease of installation in tight spaces, around obstructions, and in attic or crawlspace runs where rigid duct is not practical. The 51327 features a metalized polyester jacket that is reinforced with fiberglass scrim. This outer jacket resists puncture and provides a durable barrier against moisture and air leakage. The inner core is constructed from a double-ply black polyester material that holds its shape under compression and provides smooth, consistent airflow with minimal turbulence. Surrounding the core is R-6.0 formaldehyde free insulation. R-6.0 insulation meets the thermal performance requirements for most residential and light commercial HVAC duct installations, helping reduce heat gain or loss as conditioned air travels through unconditioned spaces such as attics and crawlspaces. This duct is UL listed, confirming it meets nationally recognized safety and performance standards. HVAC professionals installing this duct on residential new construction, retrofit, or replacement projects will find it compatible with standard 8 inch collars, boots, and duct connectors. The product ships in a box, making storage and transport on job sites straightforward. It is a dependable choice for supply-side flexible duct runs requiring R-6.0 thermal performance in an 8 inch diameter configuration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMetalized polyester jacket reinforced with fiberglass scrim for durability and moisture resistance\u003c\/li\u003e\n\u003cli\u003eDouble-ply black polyester inner core provides consistent airflow and shape retention\u003c\/li\u003e\n\u003cli\u003eR-6.0 formaldehyde free insulation meets thermal requirements for residential and commercial HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Hart Cooley 51327 delivers UL listed, R-6.0 insulated flexible duct in an 8 inch by 25 foot configuration, built for professional HVAC air distribution work in residential and light commercial applications.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HART COOLEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51327\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation R-Value\u003c\/strong\u003e: R-6.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Type\u003c\/strong\u003e: Double Ply Black Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Metalized Polyester with Fiberglass Scrim Reinforcement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Venting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage\u003c\/strong\u003e: Boxed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL Listed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51121049567538,"sku":"051327","price":115.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304878531.jpg?v=1777746977","url":"https:\/\/voomisupply.com\/products\/hart-cooley-51327-hc-f216-metalized-insulated-flexible-duct-r-6-8-inches-x-25-feet","provider":"Voomi Supply","version":"1.0","type":"link"}
