AC InfinityFlexible 6-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

I’m satisfied with the AC Infinity 6-inch ducting. The four-layer design feels durable and doesn’t tear or collapse when bent, unlike some thinner options I’ve used before. It was easy to install, fits standard 6-inch vents well, and the included clamps were helpful. Compared to other ducting I’ve tried, this one holds its shape better and feels more heavy-duty. It’s flexible enough for tight spaces but still keeps good airflow. It met my expectations for quality and performance.

At the beginning I was afraid to buy because I need it for a kitchen exhaust fan unit, I read the reviews and I took the risk; I installed today and it worked properly, is a heavy duty material I highly recommend it this item.

This dryer hose fit perfectly. The quality is amazing. The durability is awesome. Very easy to put together and not actually like the color black.

Very easy to work with, was about to tear my hair out with the OEM ducting. the included clamps are lifesavers aswell. Reccomended!

I bought a whole house fan from Lowe's, the advanced kind with a grill attached to the ceiling connected to about 6 feet of flex duct, with the motor at the other end, which draws hot air out of the house and puts it in the attic where it is expelled outside via various vents. Works great in our house, but I did a variation for the one I just bought for the garage. I, being a lifelong metal man with 20 years in ductwork, used my know how to build a plenum box and stub out 3 intakes, each 12 inch round, and instead of using the grill provided with the fan, I attached flanged box to my plenum, and ran this 12 inch flex out to a box I made for each of 3 rooms. I had grills already laying around, and made the flange to fit each grill. I put volume dampers in the 2 shorter runs to balance the intake volume if necessary. The ceiling is 11' 5",, and this the reason I "zoned" the garage, shop and rec room- one intake would not adequately pull heat out of the other 2 ceilings. Now, some tips. I made my collars 11 7/8" outside, and I still fought each connection. You could make your collars 11 3/4" and you wouldn't regret it. The reason I gave 4 stars is the material will tear if it encounters a sharp edge, like the overlap, or a burr on the edge. I recommend you have some silver tape handy and tape over the overlap and file any burrs on the outside edge. Crimping the edge will cause the same problem, so I don't recommend you hand crimp or buy start collars that come pre crimped. The metal drawbands are decent, and phillips bit in a battery drill did the trick. When you go to fit the flex on your start collar turn the excess fabric back (like you were trying to turn it inside out) to get it out of the way. It wouldn't hurt to tape metal to flex before you band it, I did. I use 3M x 3" wide. I cut my first run at about 20 feet, using wire cutters instead of snips. that left enough for my second run. I have one more to do, but I fired the fan up and it worked as expected. I'm sure I'll be pleased when the ceiling is installed. I hope these tips help you gitrdun.

Perfect fit to standard HVAC duct fittings, flexes easily, but the wire wrap creates a good structure to minimize risk of kinking in a sharp bend.Very good quality.

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.

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.
