Constructed with a metalized polyester jacket, this sleeve provides R-6.0 thermal insulation without a rigid core, allowing it to flex and conform during installation. The F206-rated insulation is formaldehyde free, which is important in occupied residential and commercial spaces where indoor air quality standards apply. At 5 feet in length and 16 inches in diameter, it suits large-trunk or main-branch duct applications. HVAC technicians and sheet metal installers are the primary trades working with this product.\u003c\/p\u003e\u003cp\u003eThis sleeve is used in forced-air HVAC systems where flexible duct connections are needed at air handlers, plenums, or large branch runs. The 16-inch diameter makes it appropriate for high-volume trunk lines in residential or light commercial installations. The no-core design allows the sleeve to be slipped over existing duct ends or collars without removing rigid ductwork. It is well suited to attic, crawlspace, and mechanical room applications where some flex and thermal performance are both required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMetalized polyester jacket provides a durable, reflective outer surface for radiant and conductive heat resistance\u003c\/li\u003e\n\u003cli\u003eR-6.0 insulation value meets common energy code requirements for supply duct insulation in conditioned and unconditioned spaces\u003c\/li\u003e\n\u003cli\u003eFormaldehyde free F206 insulation suitable for use in occupied residential and commercial buildings\u003c\/li\u003e\n\u003cli\u003eNo-core design allows flexible installation over collars, fittings, or existing duct ends\u003c\/li\u003e\n\u003cli\u003e5-foot length provides sufficient material for most single connection or short-run sleeve applications\u003c\/li\u003e\n\u003cli\u003eUL Classified construction for use in listed duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flexible duct sleeve for use in 16-inch diameter HVAC duct systems requiring R-6.0 insulated connections at air handlers, plenums, or branch collars.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of flexible duct sleeves is typically performed by licensed HVAC technicians or sheet metal workers in accordance with SMACNA guidelines and local mechanical codes. Power down the air handling system and confirm the system is depressurized before cutting, repositioning, or connecting any duct components. Secure both ends of the sleeve with approved draw bands or metal clamps and seal with listed duct mastic or UL 181-rated tape to maintain an air-tight connection. Do not compress or kink the sleeve, as this reduces effective insulation performance and airflow capacity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Metalized Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Value\u003c\/strong\u003e: R-6.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Type\u003c\/strong\u003e: No Core\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: F206 Formaldehyde Free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL Classified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage\u003c\/strong\u003e: Boxed\u003c\/li\u003e\n\u003c\/ul\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: 11000616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51672642617650,"sku":"11000616","price":71.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46ba4222711485158f36d00863d26f0f.jpg?v=1787970250","url":"https:\/\/voomisupply.com\/products\/hart-cooley-11000616-flexible-duct-sleeve-16-in-r-6","provider":"Voomi Supply","version":"1.0","type":"link"}
