Description

  • The ATCO Rubber 031-4 Premium 4-Inch x 25-Foot R-8.0 Insulated Silver Flexible Air Duct (Part Number 13102404) is a commercial-grade ventilation solution engineered to deliver superior thermal performance across demanding residential and light commercial HVAC networks.
  • Masterfully constructed with an airtight, double-ply polyester inner core encapsulating a heavy-gauge spring steel wire helix, this low-friction flex pipe guarantees maximum system airflow velocity while permanently preventing insulation fiber erosion into the active airstream.
  • Wrapped inside a thick blanket of formaldehyde-free fiberglass insulation providing a high-efficiency R-8.0 thermal defense barrier, the entire core assembly is protected by a tough, tri-directional scrim-reinforced metallized vapor jacket that aggressively resists punctures and tearing on the jobsite, ensuring code-compliant, UL 181 Class 1 certified utility across high-demand heating and cooling runs.
