VEVOR 6 Inch Insulated Flexible Duct R-6.0，25 Feet Long with 2 Duct Clamps, Heavy-Duty Three Layer Protection Air Ducting Hose for HVAC Heating Cooling Ventilation and Exhaust Ductwork Insulation

This flex duct works good. Easy to install. The outer aluminum wrap is thin but doesn't rip easily. It's easy to cut using a razer. The insulation is decent. The clamps are no good though. The quality of the clamps is fine, but the screw takes a lot of effort to move. I ended up using large plastic zip ties instead of the clamps. Overall I'm happy with this purchase. Packaging was very good.

So whoever built my house decided to install a bathroom fan with no vent to the outside. Naturally, I had to correct this but that involved threading this duct through a pre-existing ceiling - 15 feet then a left hand turn then 15 more feet to the outside. This product made the journey. It's a sturdy duct. It got dragged over rebar, no problem. It handled being tied to a dryer brush, no problem. The outside never tore. The metal rings never got bent out of shape. It's so sturdy that it was kind of a problem, since it could NOT squish its way past pipes and wires. It also stops dead if it hits the pointy part of a screw. It doesn't rip, it just get caught then refuses to move. Because of this, I ended up having to open the ceiling in one spot to get it around a big pipe and two exposed screws. For anyone looking to do a similar project, I recommend using the smallest duct possible (I bought 4inch but I really wish I had bought 3inch). I'd also reconsider using an insulated duct, as the insulation adds two inches to the width of the duct and it doesn't squish down as much as you'd hope it would. And use the dryer-vent brush strategy for getting it through your ceiling. First, thread a long dryer-vent brush through the ceiling, then tie the brush end to the duct, then pull the other end of the brush - thus dragging the duct into the ceiling. But I'm glad I bought what I did. In the end, there is surprisingly strong airflow through the duct (I bought two and connected them to go the distance), and I credit the insulation with tamping down noise from the bathroom.

I recently purchased a home. After being in it for a year or so we’ve come to notice it was a flipped house. One thing we noticed is our upstairs was not cooling right in 2 of the bedrooms. Checked the vent and no pressure. Followed the hvac lines and someone thought it was a great idea to split a 6in into 2 rooms. Ran another line to the box with this flex duct and better flow, cooler rooms, happier hvac.

Bought this for a double wide AC line. I'd say it's a little thinner that I was hoping for on the outer layer, but I installed and it will be fine, if I can keep the critters off of it.

Worked as suspected. Great length option when installing and connection to soffit vent. I love it !!!

Surprisingly good. The actual duct is thick and poly like. Does not tear easily. Fits well. Comes with clamps.

I have bought several rolls of the major name brand of this, at my local lowes So I know what im working with. When I went to install this duct I found the inner duct to be easily torn, even with light pressure. I had to use kid gloves and even then I had to tape a couple tears. The insulation inside seemed to be on par with the big brand, the outer shell is a little weak as well, but thats much less of a problem.

Alright product - used a custom install - happens to fit the 5.5 " duct work for a zafro portal AC - was kind of tight to slide on tube, but in and came out alright - try getting r6.0 this way with other heat jackets on sale out there!!! while one has slide the hand inside the pull the duct right through - still works as intended. Actually r6.0 compared to other HVAC jackets on sale out there.

Flexibel verlegbar

J'en ai installé deux de 25 pieds pour passer de l'air chaud récupéré de mon foyer au bois du sous sol avec une turbine entre les deux et c'est parfait, l'isolation est correct ainsi que l'intérieur en aluminium, le revêtement extérieur est quand même assez solide vu le brassage que nous lui avons occasionné.

Ottimo di altissima qualità e il prezzo è veramente unico

Conforme à la description. Facile à utiliser

It came compressed in a box and with some large hose clamps. Quality is pretty good. I had no issues installing the product. Sturdy and insulates nicely. 10/10 may buy again.
