Description

  • The Generic Flexible Silver Jacket Air Duct is a commercial-grade, R-4.2 insulated ventilation line engineered to deliver energy-efficient, whisper-quiet air distribution across low-to-medium pressure HVAC networks.
  • Constructed with a heavy-duty double-ply polyester inner core supported by a robust zinc-coated spring steel wire helix, this highly flexible pipe expands cleanly over connections without collapsing or binding around tight structural framing bends.
  • A certified R-4.2 formaldehyde-free fiberglass insulation wrap completely surrounds the vapor core, shielded by a metalized silver polyester jacket that stops condensation buildup and minimizes temperature loss.
  • Perfect for sheet metal contractors, HVAC installers, and building maintenance supervisors, this UL 181 Class 1 air connector slices field installation time and hooks up effortlessly onto standard 4-inch round collar take-offs.
