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. Review: High quality - I've used a lot of different ducting over the years for various projects, this is one of the higher quality, if not highest quality ducts I've used. Its expensive but worth it. It doesnt feel like its piece of tissue paper, and can handle a decent amount of abuse, at least as far as flexible ducting it concerned. ## Features - Designed for ventilation applications including HVAC, dryer, grow rooms and tents. - Four layer design makes it more durable and resistant to leaks, tears, and cuts. - Steel-wire spiral structure is flexible and easy-to-install in hard to reach places. - Constructed of Aluminum and thermoplastic, tube can be shortened for various applications. - Ducting Size: 4” | Length: 25 feet | Includes two stainless steel 4" duct clamps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071LHCFZ8 | | Best Sellers Rank | #5,132 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #4 in HVAC Ducting | | Brand | AC Infinity | | Brand Name | AC Infinity | | Color | Black, Silver | | Customer Reviews | 4.7 out of 5 stars 8,301 Reviews | | Item Dimensions L x W | 300"L x 4"W | | Item Length | 300 inches | | Item Weight | 0.27 g | | Manufacturer | AC Infinity | | Material | Aluminum , Stainless Steel | | Material Type | Aluminum, Stainless Steel | | Nominal Wall Thickness | Greater than single-layer thickness inches | | Number of Flutes | 1 | | Outside Diameter | 4 inches | | Product Dimensions | 300"L x 4"W | | UPC | 854759004952 | | Unit Count | 25 Feet | ## Product Details - **Brand:** AC Infinity - **Color:** Black, Silver - **Item Length:** 300 inches - **Item Weight:** 0.27 g - **Manufacturer:** AC Infinity - **Material:** Aluminum, Stainless Steel - **Nominal Wall Thickness:** Greater than single-layer thickness inches - **Outside Diameter:** 4 inches - **Product Dimensions:** 300"L x 4"W - **UPC:** 854759004952 ## Images ![AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long - Image 1](https://m.media-amazon.com/images/I/61gDYGO1+EL.jpg) ![AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long - Image 2](https://m.media-amazon.com/images/I/617bT01GrvL.jpg) ![AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long - Image 3](https://m.media-amazon.com/images/I/61sGtDyCAnL.jpg) ![AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long - Image 4](https://m.media-amazon.com/images/I/61laljY0z1L.jpg) ![AC Infinity Flexible 4-Inch Aluminum Ducting, 25-Feet Long - Image 5](https://m.media-amazon.com/images/I/51RX5P0swZL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: It seems like the bad reviews are about size and come from march of 2020. Did you switch manufacturing or something? If so had it been resolved yet?** A: The problem was, it just said it was 4" in diameter, but did not point out that the 4" were outside diameter. The product itself is probably good. I needed an air vent hose with 4" inside diameter, so it can go over a pipe with 4". I wonder why somebody would be interested in the outside diameter for these hoses anyway. I ended up buying a non insulated hose at Home Depot, where I could take my own tape measure to see with my own eyes what I am buying. **Q: Has anyone else noticed that none of these are actually 25ft in length?** A: I had to send mine back, because of the diameter was not what I needed. There was some confusion, I had thought it would fit on a 4" connection, but it did not. So, I bought something else at a local store, where I could physically measure the ID. **Q: Can this be used as an hvac supply duct? (heating and ac)** A: If it can be used for a dryer vent, it CAN be used for HVAC , the dryer produces more heat that a home furnace. **Q: Come in white??** A: Hi there, Thank you for reaching out to us! I'm sorry but we do not have these available in a white option.

Its expensive but worth it. It doesnt feel like its piece of tissue paper, and can handle a decent amount of abuse, at least as far as flexible ducting it concerned. ### ⭐⭐⭐⭐⭐ Great flexible duct! *by B***J on July 21, 2026* 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! ## Frequently Bought Together - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - Hon&Guan Soffit Vents 4 Inch, Round Vent Cover Air Vent with Built-in a Fly Screen for Bathroom Exhaust Vent Office Home (ΓΈ100mm) - EesTeck 4" (Diameter) Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps (4Pcs, 91mm-114mm) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/57113912-ac-infinity-flexible-4-inch-aluminum-ducting-25-feet-long](https://www.desertcart.co.za/products/57113912-ac-infinity-flexible-4-inch-aluminum-ducting-25-feet-long) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-16*
