VIVOSUN 8 Inch Flex Aluminum Ducting, 25 Ft Air Duct with 2 Clamps, Silver

This 4-inch VIVOSUN aluminum duct has been a great addition to my ventilation setup. The 25-foot length gives plenty of room to route it where needed, and it is flexible enough to work around corners without being difficult to install. It feels well made with its multi-layer construction and has held up well in use. The duct keeps its shape nicely, connects securely to standard 4-inch fittings, and works well for HVAC, exhaust, or 3D printer ventilation projects. Overall, a durable and versatile duct at a good value. Very happy with it.

Great product at a reasonable price Quick Delivery Thank you

This 4-inch aluminum foil ducting is extremely well made and far sturdier than I expected. The aluminum layering feels thick and reinforced, not cheap or flimsy, and it holds its shape perfectly once installed. I really like the black outer layer—it looks clean, professional, and helps with light control compared to standard silver ducting. The hose is flexible enough to route easily, yet strong enough that it doesn’t collapse or kink. The 8-foot length was perfect for my setup, and the included clamps fit snug and secure with no air leaks. Overall, this is a high-quality, heavy-duty vent hose that feels reliable and built to last. Great for HVAC, dryer vents, or exhaust fan systems. I would absolutely buy this again and recommend it to anyone looking for durable, trustworthy ducting.

Great quality. Only issue is ordered 16ft and fully extented is 12 ft. Had to order a another one.

Good product. Much better tan the plain aluminum one!

Excellent

Great item fast shipping and great product for the price

Even though my opening was a bit bigger at about 6.5”, it still stretched to fit without ripping or tearing. It held its shape well and stayed flexible the whole time. The material feels solid enough for regular use and didn’t feel like it was going to fall apart when stretched. One thing to keep in mind is heat. If you’re moving hot air through it, the duct itself will let heat escape, so wrapping it with insulation on the outside would help keep more heat in. Overall, it’s a good, reliable duct for basic venting jobs.

Inspiriert durch Manfred Welding hat mein Keller nun auch eine Absauganlage erhalten. Der Schlauch ist solide aber nicht störrisch. Er lässt sich gut durchschneiden und auch über den Tisch bewegen. Als Einsaugtrichter habe ich mir aus 20x20mm Quadratrohr einen Halter geschweißt. Damit kann ich jetzt überall auf dem Tisch einfach den Schlauch Positionieren. Generell ist ein Staubsauger schon ein muss, sofern das Werkzeug einen Anschluss dafür hat. Da das aber nicht 100%ig alles einfängt und z.b. beim Laserreinigen der Arbeitsbereich zu groß dafür ist, wird das jetzt damit gemacht.

I actually bought this for my ferrets and they absolutely love it. Thickness is okay for what it is. I can't however comment on installation, comparability or the included accessories as I didn't use them.
