5 Inch Insulated Flexible Duct - 25 Feet, R4.2, For Heating & Air Conditioning HVAC Systems

Great flexible duct at a great price point - a lot cheaper than the local hardware stores for the exact same thing. Fitment over my 4" soffit vent it pretty tight, but it can be done. Insulation seems like decent quality. The interior duct itself seems durable too (I pulled it pretty hard to "stretch" it over the 4" soffit duct and it went without ripping. Also came with 2 hose clamps which is just a nice addition (one less thing to worry about). Now it comes vacuum packed and kind of coiled up. Once you open up the plastic it stretches out nicely (kind of like those memory foam mattresses). Easy to get to the shape that you want. The entirety of the duct was wrapped with insulation as well - so it doesn't appear to be "cheap". Use - I'm personally using this for my bathroom exhaust vents. Running from the exhaust vent to the soffit vent with this line. Overall - it's great that this is available on Amazon - no dealing with the store, parking, ghetto people, paying higher prices at the store etc.

The inner "foil" layer was much tougher than another reviewer said. It's more of a "mylar" plastic silver mirror kind of material. I only needed 15 to 17 feet, so I didn't mind ruining the end I attached to a rope for pulling through the hordes of black widows and rattlers. The insulation is as expected. I did tear the outer layer just a tiny bit pulling it with a rope I'd fish-taped through a confined crawlspace trench I had to hand-excavate. Attaching it firmly to the flanges worked well however the Hose Clamp, or Radiator Clamp style items supplied were some metric size I had no socket bit for. So, picture a guy on his back in dirt with spider webs hanging down trying to use a flathead driver on his drill to tighten a long long long clamp. One spider said: Hey, how-ya-doin?" I have patience. I attached it to one flange from inside the home, the other from underneath. Both ends were easier than expected. This is a quality product, but fragile as you might imagine. Be careful of it and it's tough enough and a good value.

A great product. Highly recommended.

Awesome

The Cuchiilo 4‑Inch Insulated Flexible Duct seems to be made from solid, good‑quality materials. The insulation is thick, the outer layer feels durable, and the flexibility is helpful for maneuvering it into tight spaces. Once installed, it does its job well and provides a nice upgrade over cheaper, flimsy options. That said, attaching the ductwork to solid pipe was more difficult than expected. The inner layer tends to tear easily when trying to stretch it over rigid ducting, even when being careful. I eventually got it secured, but it took patience and extra tape to reinforce the connection. Overall, it’s a quality duct once it’s in place, but be prepared to take your time during installation or use a connector to make the process easier.

Works well, but would not recommend cutting it up at all like I did. Does not cleanly cut well. Will makes clouds of micro dust yellow glass everywhere! And coat everything. I removed the inner liner to wrap my rigid metal ducts I already had and it all kinda started falling apart easily. I used the prices to individually mummy wrap my ducts with lots of foil tape.

Not much to say here: it’s 6" insulated flexible ducting, and it did the job perfectly. Easy to work with, solid insulation, and exactly what I needed for my project. Sometimes you just need something that works without any drama—and this delivered. Five stars!

This product was very disappointing for two reasons. First, the inner aluminum foil duct was so thin and flimsy that it was impossible to get it onto the vent structure without tearing. I finally just wrapped aluminum tape around it to stiffen and reinforce it, and that worked marginally. Second, the duct clamps were not nearly long enough to wrap around the inner duct. They couldn't even wrap fully around the vent structure which is smaller than the duct! I had to use some other short clamps to attach to these to make them long enough to work. If I had not already cut the section of duct that I needed, I would have returned the whole mess. Don't waste your time on this junk!

Il tubo è molto resistente e lo consiglio vivamente....

Works great for outdoor ducting to a diesel heater

Kann mich nicht beschweren

Great product with very reasonable price. Very easy to install on my new ventilation ducting to bring fresh air onto my bedroom, almost noise from the ducting fan disappeared since replacing this fibre wood one. So quiet I don’t even know the fan is on. Highly recommended

Perfecto para lo que queria
