AC Infinity Flexible 8-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

I got this pipe to run an extra length for a laser I was using. It was really easy to install, has a good thickness to the pipe and seemed to be very durable. I did not have any leakage from the pipe or around the connectors when I was using this pipe. It comes in several different lengths and diameters. I do recommend this pipe and will buy again if I need another piece of duct.

This is a high quality air duct hose! It is thicker than just a simple plastic hose and fits perfectly in my portable AC unit. It seems like it will be very durable, but only time will tell. This is a great value for the money.

The material is excellent and has a higher end material feel. Installation is a breeze that exhausts or supplies much needed air with no problem.Will recommend to any serious grower that wants a high quality product that looks as well as it functions!

We needed to extend a portable A/C duct so we could move the unit further from the window. The unit has an unusual 7" duct (most are 6") so I had to look for solutions. This seem to be working well, with a few caveats:- it releases heat (not really a fault since it's not designed to retain heat). The A/C is pushing hot air through this duct and a good amount of heat is lost inside the house before the air gets outside. I could try insulating it, but that seems silly since it's not a permanent A/C unit.- it extends its full length (again, not really a fault). This duct is made of a mylar-like material with no stiffness, which is not a bad thing. But you'll need to cut it to the proper length (scissors and wirecutters make this easy). It was kind of laughable to watch the hose expand to its full length and wiggle around the room.- the ends will need to be tied or clamped down. We used elastic shock cord, which worked perfectly. I think a metal band might be too hard or stiff for this material if you're attaching it to another duct like we were... the mylar might tear.All in all, a quick and effective solution to our needs. Good quality in a light expandable duct, and a fair value as well.

The thin "rubber" coating seems to give it a bit more durability. Be aware that this ducting is "NOT" insulated, so is therefore unsuitable for a/c exhaust.

Husband approves. He said it was a pretty tight fit however that's good. Used in ceiling for diffusers. Also cut easily

Great duct vent. Very high quality and works perfectly. Comes with two clamps.

I wanted something a little classier than exposed silver ducting as this was going in a location that can be viewed by visitors. This meets that criteria. The exterior is a matte/somewhat shiny black finish covering over the silver that makes it look like it is hiding in plain sight. Nice stuff.
