Flexible 6-Inch Aluminum Ducting, 25-Feet Long

This 6-inch aluminum ducting feels well made and durable. The material has a sturdy, reinforced structure, and the four-layer design gives it a strong and reliable feel. It holds its shape well once positioned and doesn’t feel flimsy. The length is generous and provides plenty of coverage. The black exterior also gives it a clean, uniform appearance and does a good job of hiding dust and marks over time. Overall, the build quality is solid, and it performs as expected for ventilation and exhaust setups.

The four layer build is the real difference here compared to thinner single layer ducting. The inner aluminum foil layer is fire resistant, and the outer thermoplastic layer adds real resistance to tearing and punctures while routing it through tight spaces. The internal steel wire spiral keeps the tube round and open even after bending it around obstacles, rather than collapsing or kinking the way cheap ducting tends to. It stretched to full length without issue and the diameter fit snugly over a standard inline fan connection, no fighting to get it seated. The two included clamps are good quality and cinch down tight for a proper seal. Works well whether the application is a grow tent, dryer vent, or general exhaust routing.

The AC Infinity Flexible 8-Inch Aluminum Ducting (8 feet long) is a fantastic choice for anyone setting up or upgrading a ventilation system. I use mine with an AC Infinity inline fan, and the results have been excellent—it moves air efficiently while staying strong and secure. The four-layer protection (dual aluminum foil, PET, and steel wire spiral) makes this ducting not only flexible but also very durable. It doesn’t tear or kink easily like cheaper ducting, and the extra thickness helps keep it from collapsing under pressure. The flexibility makes it easy to route through tight corners, and installation was straightforward with the included clamps. ✅ Pros: Heavy-duty four-layer construction for long-lasting use Flexible design makes installation easy, even in tight spaces Works perfectly with inline fans, grow tents, hydroponics, and HVAC setups 8-foot length is versatile for most setups Comes with sturdy clamps for secure attachment ❌ Cons: A little stiffer than thinner ducting, but that’s the tradeoff for durability At 8 feet, you may need extensions for larger setups 💡 Tips: Use with an AC Infinity inline fan for maximum airflow efficiency. When cutting to size, make sure to trim cleanly and secure ends tightly with clamps to avoid air leaks. If using in a miner room or greenhouse, pair it with a soffit vent to direct air outside effectively. Avoid bending too sharply—keep smooth curves for better airflow. Bottom Line: This ducting is built to last and does its job extremely well. Whether you’re cooling a miner setup, venting a grow tent, or upgrading your HVAC system, the durability and flexibility make it worth the investment.

quality of materal is good but watch the length. I got one a few months ago to exaust a fan outsid and during a rain storm a cat tried to get in through it and it fell from the ceiling it was mounted on and the cat freaked out and riped it up. So I got a new one ( ducting not cat ) and want to install it and its 1.5ft shorter. Kinda odd being I just went to my history and hit Buy Again. I had to remount the fan closer to the exit spot. other then cat proof and length issues its a good product.

Very flexible and well made. Used it for a bathroom vent fan and the length worked out perfectly to let me route it to the vent at the top of my attic.

These ducts are really high quality. They are the size theu claim to be. They are light weight. They expand to the proper size easily, and almost "click" back to smaller lengths instead of becoming a mess. They do have a little thing of tape on each end, that is kind of hard to get off, not that hard, but ya might groan a few times. With the included clamps they form great seals and are easy too attach. They take a beating too... worth the extra few bucks in my mind. I have horror stories about lesser flexible ducts.

Metal dryer vent from Lowe's was very flimsy and tore easily causing dryer to not dry well. I came on Amazon to find a replacement and there are tons of Chinese items. I ended up checking out virtually all of the options and landed on one that also had a coating on the outside to make it stronger. I can say that the plastic coating does exactly that: it helps control the hose while installing, has a good feel, and is sealed properly around the vent. My item came properly sized and it fit around both hose hookups. You'll notice reviews saying some of the hoses out there are too small which renders it unusable. Also I recommend getting clamps like the one below or something similar which makes installing the hose WAY easier and the cost of the clamp is less as well. -POWERTEC 70120 4 Inch Key Hose Clamp
