Hart Cooley 51332 Hc F216 R-6.0 Insulated Flexible Duct 16 Inches X 25 Feet

Product Description

The Hart Cooley 51332 is a metalized insulated flexible duct designed for HVAC air distribution systems. It measures 16 inches in diameter and comes in a 25-foot length, making it suitable for connecting air handlers, plenums, and diffusers in residential and light commercial HVAC installations. This product is part of the HC F216 series and is built to handle standard supply and return air venting applications where flexibility and thermal performance are both required.

The outer jacket is made from metalized polyester that is reinforced with a fiberglass scrim. This construction gives the duct its durability and resistance to tearing during installation. The inner core is a double-ply black polyester design that maintains airflow integrity under typical system pressures. Between the core and the outer jacket sits R-6.0 formaldehyde-free insulation, which helps minimize heat gain or loss as conditioned air travels through the duct. The R-6.0 rating meets common energy code requirements for flexible duct insulation in many jurisdictions across the United States.

HVAC technicians and contractors rely on insulated flexible duct like the 51332 when running supply lines through unconditioned spaces such as attics, crawl spaces, and mechanical rooms. The flexibility of the duct allows it to navigate around framing, joists, and other obstructions without the need for rigid fittings at every turn. This saves installation time and reduces labor costs on the job. The duct is UL listed, confirming it has been independently tested for safety and performance. It ships boxed for easy handling and storage on the job site.
