AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust

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 useFlexible design makes installation easy, even in tight spacesWorks perfectly with inline fans, grow tents, hydroponics, and HVAC setups8-foot length is versatile for most setupsComes with sturdy clamps for secure attachment❌ Cons:A little stiffer than thinner ducting, but that’s the tradeoff for durabilityAt 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.

Used this for a portable AC unit. OEM hose became brittle from the heat and was no longer serviceable. This has held up well and seems like it may last a lot longer.

This is great for those awkward areas that don't quite line up. sturdy and thick, yet very flexible.

I've had a couple of these 8" ducts in use for over a month, which have been repositioned repeatedly while handling nonstop blower output, and have had no problems so far. The multiple layers and the opaque black outside are well-suited for maintaining light discipline for plants that require it. The ductility is par for these kinds of ducts but it does feel more resilient than what you might pick up for your dryer. The ends have zero additional tolerance so getting then over the rim of a duct inlet or blower fan sucks, but that's pretty typical for flexible ducts.Recommended. It seems better quality than the average flexible duct and I don't think it costs too much more, although I didn't comparison shop. If you can get one with equal quality and ends that expand slightly to reduce the pain of getting them attached, I'd go that route, but this duct is probably still going to be better than most.

Product is as described. we use it to vent portable A/C units and it works as expected. We have two and they are an excellent solution.

Quick to install and durable as it is still on my dryer after 3 years.

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
