AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection

This 6-inch aluminum ducting feels well made and durable. The material has a sturdy, reinforced structure, and the four-layer design gives it a strong and reliable feel. It holds its shape well once positioned and doesn’t feel flimsy. The length is generous and provides plenty of coverage. The black exterior also gives it a clean, uniform appearance and does a good job of hiding dust and marks over time. Overall, the build quality is solid, and it performs as expected for ventilation and exhaust setups.

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.

Great item. We have purchased this one over the years with no issue. It does it's job in a hot tent grow room atmosphere.

Seems to be good quality but did rip a little when attaching to duct work.

Superb quality

Well built pipe very ridged

I went searching for a more 'permanent' vent product for use in venting bathroom exhaust fans to the outside. I was skeptical to say. However, upon arrival it was clear this product WAS indeed several levels of quality above the typical aluminum foil exhaust duct. As such, I was pleasantly surprised and impressed by the quality. So, if you are looking for something to go 'behind the wall' or 'above the ceiling', this should do the trick. As a 'flag' to denote this as a legitimate comment ~ go Bengals and may we please find an offensive line!

First and foremost, this works perfectly with my BLACK+DECKER BPP08HWTB Portable Air Conditioner https://www.amazon.com/gp/product/B08TH93TGG/ It fit right over the exhaust connector that leads to the window, and the exhaust hookup that connects directly to the AC unit. The only CON is that I may have over-tightened the clamp (it comes with 2x clamps to create a perfect seal) that leads to the exhaust hookup to the AC unit, because there is a little bit of heat leakage at the hookup point, but I plan to seal it with some Heat Resistant Tape. It's not a perfect seal at the unit itself, but it's pretty close. The first time I had the clamp too tight and the hookup wouldn't line up and seal at all, but after sliding the tube back a few CM, and loosening the clamp a bit, I was able to get it pretty close. Anyhow, for about $25 bucks, I HIGHLY RECOMMEND THIS TUBE! Now I can have my AC Exhaust in the bedroom window, and blow cold air in my living room! If I could find a use for another, I'd purchase again. Hopefully it is as durable as it seems, because if so, I won't need a backup. Will update with pics later, just wanted to rate this item after hooking it up, it was that good! ### Update ### Nearly 4 months into ownership, and it is still holding up, and in nearly the same condition as when first purchased! A friend accidentally stepped on it while traversing my domicile, and despite the hose being slightly bent (the slinky-like wire corkscrewing that runs the length of the hose allowing it to retain its shape), it was intact, no puncture or tearing! I'm amazed, as I was all but sure it would be destroyed, or at the very least need a patch kit.

Excellent quality product, well packaged.

I'm using this AC Infinity 6" ducting for my "tomato" grow tent, and it's been working wonders! I was worried about finding a ducting that could withstand the humidity and temperature fluctuations, but this four-layer protection design has been durable and resistant to leaks. The internal layer's fire/flame resistance and the outer layer's dual PVC thermoplastic provide great protection, while the internal steel-wire spiral makes it flexible and easy to install in hard-to-reach areas. What's even better is that you can cut the tube to your desired length, making it the perfect fit for my tomato grow tent. I didn't need to worry about any leakage, thanks to the two stainless steel duct clamps included. This product is affordable, durable, and flexible, making it a great value for my needs. I highly recommend this AC Infinity ducting for anyone in need of reliable and customizable ventilation for their grow tent. It's a great product that has exceeded my expectations and I'm confident it will continue to work well for my "tomato" plants. Its also a great brand for similar price to lesser brands.

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。

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
