Hart Cooley 27823 F218 Series Insulated Flexible Duct 4 Inches X 25 Ft R-8

Product Description

The Hart Cooley 27823 is a UL Listed insulated flexible duct from the F218 Series residential product line. It is designed for use in HVAC air distribution systems where insulated ductwork is required to maintain airflow efficiency and prevent energy loss. This flexible duct measures 4 inches in inside diameter and comes in a 25-foot length, making it a practical choice for a wide range of residential installation jobs. HVAC technicians use insulated flexible duct to connect air handlers, plenums, and branch takeoffs to supply registers throughout a home or light commercial space. The polyester core provides structural integrity and flexibility, allowing installers to route the duct around framing, joists, and other obstructions without the rigidity limitations of sheet metal ductwork. The metalized polyester jacket gives the duct its silver finish and helps protect the insulation layer from damage during and after installation. An R-8 insulation rating means this duct meets or exceeds energy code requirements in many jurisdictions, reducing heat gain and heat loss as conditioned air travels from the air handler to the living space. Higher R-value flexible duct like this R-8 product is commonly required in unconditioned spaces such as attics and crawl spaces where temperature differentials are greatest. The round shape and standard 4-inch diameter make this duct compatible with a wide variety of fittings, collars, boots, and takeoffs used in residential HVAC work. Each unit comes individually boxed, with one 25-foot section per package. This product is suitable for forced-air heating and cooling systems and is a go-to option for HVAC installers working on new construction or replacement ductwork projects.

• R-8 insulation rating for energy-efficient air distribution in unconditioned spaces
• Polyester core with metalized polyester jacket for durability and flexibility
• 4-inch inside diameter by 25-foot length, UL Listed for residential HVAC use
