Product Overview

The Master Flow 6 in. x 25 ft. Insulated Flexible Duct R8 Silver Jacket is used in standard Heating and Air Conditioning (HVAC) systems and some venting applications.

  • 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 vs. non-galvanized wire

  • Insulated duct features a maximum temperature rating of 200°F
  • Always install per instructions and seal using approved mastic or sealant (or approved tape)

Customer Reviews

Rated 4.8 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Product is durable and easy to work with. I ordered two. Product is durable and easy to work with. After shaking and pulling, both were 22 ft long not 25 ft. I really missed the extra 6 feet but made it work. I got 2 10" also both were 25ft. Tip:I recycled all the insulation from the old flex duct . June 13, 2011
Rated 4.0 out of 5.0 by Flexible duct You have to be extremely careful when installing this flex duct through a tight-fit opening, as the outer vapour barrier could rip easily. It looks strong, but will not tolerate too much of a pull. I ripped mine when guiding it through an opening in a gypsum board wall which does not have very sharp edges. June 24, 2014
Rated 5.0 out of 5.0 by Re-placed metal ductwork This was ordered on-line for pick-up at local store so i would be sure to get the right product even through they had in available. Service was good and followed up with email telling me it was ready for pickup before I was ready! It replaced an old metal duct I needed for a vent in the kitchen that was covered over with a new floor by mistake. I felt great pride in being able to still be able to crawl around in my crawl-space at 62 and hook this up with no problem. December 6, 2011
Rated 5.0 out of 5.0 by Replaced Flex ductwork The insulated Flex Duct worked out just fine. I had a lot of leakage in the piece I replaced. February 3, 2014
Rated 5.0 out of 5.0 by Great duct Easy to install, Works like it's suppost to. Not to heavy to drag around under a house. May 7, 2013
