AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long

As described, works well. Very happy with it. Material is actually strong.

I normally use hard ducting, but the prices have gotten ridiculous. Plus, where you have to work around obstructions flex duct is so much easier. You just have to accept that the airflow is not going to be what rigid delivers. And as flex duct goes you can't do any better than this. Absolute top quality. I've purchase it before, along with other brands, and I just purchased this again. Forgot to install a code-required vent fan in the laundry room and I needed to work around everything that already had been installed. I got wiring run for an inline fan and needed to get from the register boot to the fan, and then to the wall vent cover. There were several items in the way so this made the run pretty easy, although I still try to keep the angles as low as possible and the runs as straight as possible. And I always fully stretch the duct to keep generated turbulence to a minimum. All that said, I really like this stuff. And it does comes with two stainless steel clamps.

Replaced ALL of my ductwork in my RV. Didn't want to take a chance when I bought it second-hand. This ducting is heavy duty. Multiple layers and way thicker than what was in there from the factory. Don't hesitate to order this ducting, you will not be disappointed.

Very flexible, easy to work with. Sized well, took duct tape well and worked great with 4” fittings. -1 star because I could not get more than about 20 feet (actually closer to 19 feet) regardless of stretching it out…a perfectly flat, straight run.

I bought the AC Infinity CLOUDLINE PRO T8 to boost the air flow to a 2nd floor room. But, I wanted to try this out before I went through the trouble of cutting the duct work, etc. So, I hooked the fan up to this duct and ran it down the stairs and basically just blew the cold air from downstairs upstairs! Worked great!

Purchased to use with an inline duct blower to exhaust my BambuLabs X1C 3D printer fumes out my window. Works as expected. No complaints at all.

Yes more than meets my expectation I will buy it again and again great quality product

I highly recommend this product

スポットクーラー用の延長ダクトとして使ってます。 末端は写真のように綺麗にカットされていませんが、コストパフォーマンスが良いです

It’s a strong material I like it

Todo bien, gracias

Lo utilizo para sacar aire por medio de un extractor, me parece que tiene una excelente longitud para su precio, excelente!

除湿機ほ排熱用ホースの為購入。 size 100Φ 、ちょっと大きめでも接続できた。中々 100Φで長さ6mを越えるものがなく、良い商品に巡り逢いました。 ホースの構造もしっかりしていて、かなり伸ばせて使用できるため重宝しています。
