Frequently Asked Questions:
What are the recommended uses for this flexible duct?
This duct is designed for applications such as kitchen vent hoods, HVAC air lines, dryers, indoor gardens, grow tents and bathroom exhausts.
Can this duct be used as a portable AC Hose?
This duct will not be a good choice for portable AC applications. It will accumulate and dissipate heat exhausted by AC and keep it from coming out of the window. We recommend using a plastic duct for AC exhaust purposes, plastic will not accumulate or dissipate heat until it reaches the window exhaust.

No, this duct is made with double layer of foil and a White PVC plastic layer and is designed to transfer air. Debris transferred by vacuum will puncture the this flexible ducts.

Whoever put the dryer vent into the foundation put it on the other side of our house, so the ductwork under the house has to run approximately 27 feet. The dryer ductwork that runs under the house is broken, it's the middle of winter, wet under the house and to get under the house, someone must come into the house to get to the trap door that opens to the underside of the house (not with COVID running rampant). And the clothes are not drying properly. Lots of lint and it takes 3 hours to dry a small load. We needed extra long duct work so my husband could run it from the dryer vent out the back garage door through an old cat door. Yes! We have to step carefully down into the garage for a few months until someone can come into the house so as not to step on the hose, but the clothes are now drying properly. I'm not familiar with regular ductwork for dryers but my husband says this is super thin and fragile, but it's working as designed (by my husband). Oh! and it came the next day in plenty of time to install it.
Delivered promptly. Item was as described. Good price. Update to my previous review. I've downgraded it to a 3 because I don't think it is quite a 4" diameter. I could not get it over the 4" fittings that I've previously been able to easily get ducting over. I ended up having to cut the wire in a few rings then re-seal the slit with duct tape.
Several issues with using a multi layer hose. The inside is very rough which will collect lint if used for dryer hose. It also makes it very difficult to slide onto 4" ducting.
great deal on ducting, but the clamps are worthless, be sure to buy separate clamps, because the ones that come with the ducting is awful and cheaply made, you can't even tighten it with it stripping or jamming!
This thing is perfect. Setup a completely sealed gas dryer vent about 25' up a wall and over a large ceiling to an exterior wall in our garage. So much better than no ventilation system.
It works. I attached this to a custom fitting mounted to my window A/C unit. I can now pipe cool air into any room in my apartment since the only window the unit fits in is in a room that's rarely used. No leaks, dual layer foil for insulation, just what I wanted.
