Product Overview

The Master Flow 20 in. x 25 ft. Insulated Flexible Duct R8 Silver Jacket is used in standard Heating and Air Conditioning (HVAC) systems and some venting applications. The duct has R8 insulation which contains 50% more insulation than the standard R4.2 product. This additional insulation provides greater thermal efficiency to save energy. The product is also covered in a heavy duty, silver jacket for durability. The duct is ETL listed, meeting the UL181 standard.

  • R8 fiberglass insulation for greater insulating power
  • Flexible duct is convenient for use in multiple applications including heating and A/C systems and some venting
  • Oversized core to connect quickly and easily to standard sheet metal fitting
  • Galvanized core wire for greater corrosion resistance verse non-galvanized wire
  • Duct can be cut to length as needed
  • Insulated duct features a maximum temperature rating of 200 degree F
  • Always install per instructions and seal using approved mastic or sealant (or approved tape)
