The Master Flow 7 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket is used in standard Heating and Air Conditioning (HVAC) systems and some venting applications.

  • R6 fiberglass insulation for greater insulating power

  • Always install per instructions and seal using approved mastic or sealant (or approved tape)

March 20, 2016
I need to run 20' of the 7" duct between the 'rim" joist and the "adjacent" interior joist (space is 14-1/2").
The foundation wall line (wall that bears the rim joist) has a separation of 8-1/2" from this "adjacent"
joist.

Can the duct be temporarily compressed to pass through the 8-1/2" space without causing permanent deformation?

Rated 4.9 out of 5 by 9 reviewers.
Rated 5.0 out of 5.0 by flexible and easy to use I used various sizes of Master Flow Flexible ductwork when installing my furnace. The 7 inch ductwork is as tough and flexible as the 12 and 8 inch sizes. When installing this ductwork on Master FlowStarting collars, installation is fast and very secure. The ductwork is very flexible and able to snake through tight spaces. I definitely recommend this ductwork. September 29, 2013
Rated 5.0 out of 5.0 by Great Product! We had to replace the ducting in our finished basement as the previous owners/builder had not put insulation around the metal A/C ducts before finishing the basement, and the metal ducts were having a serious condensation problem causing spots of moisture and eventually mold on the ceiling. We cut out all the drywall in the affected areas on the ceiling and pulled out the full length of the metal ducting and replaced it with this product. It was a perfect fit and you can tell this is a quality product. The hardest part about this whole project was patching up the ceiling. =) September 27, 2011
Rated 5.0 out of 5.0 by As specified on site, good price vs HVAC dealer Easy to use, install instructions on box, works as it should August 19, 2014
Rated 5.0 out of 5.0 by Excellent product Very easy to work with. Ducting fit well over union and at A/C register. March 10, 2014
Rated 5.0 out of 5.0 by Problem solver for difficult venting. I used this product to solve a very difficult venting situation for a range hood. I was going to use standard duct work but couldn't make the turns with a rigid 90 degree elbows reducers and adapters through the overhead soffits. This worked like a charm plus it's insulated. February 12, 2013
Rated 4.0 out of 5.0 by served its purpose. It's duct work, not rocket science. You put it in. Seal it with tape and move on. Good insulation and easy to cut... Nice product. July 22, 2012
