Review: Proper stuff, sorted my dryer out! - Finally got round to replacing the rubbish old ducting on me tumble dryer, the old one was practically made of cobwebs and hope. This AC Infinity stuff is a different kettle of fish altogether! It's really sturdy, you can tell its got those four layers they talk about. Was a bit of a wrestle getting it connected up, like trying to tame a shiny silver python, but once it was on with a couple of jubilee clips, it felt solid. The 8 feet length was more than enough, had a bit to spare. Dryer seems to be working more efficient now too. Well chuffed. Review: Large Flexible Ducting - Bought this so that I could install some AC units that require large holes through the wall in a slightly different way to the manufacturers instructions. This ducting is perfect, I cut it to the desired length with a sharp knife and wire cutters, attached both ends with jubilee clips and they work a treat. This ducting was absolutely perfect for what I needed it for and delivered super fast by desertcart ## Features - Designed for ventilation applications including HVAC, dryer, grow rooms and tents. - Dual 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” (10.16 cm) | Length: 25 feet (7.6 cm) | Includes two stainless steel 4" (10.16 cm) duct clamps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071LHCFZ8 | | Best Sellers Rank | 10,302 in DIY & Tools ( See Top 100 in DIY & Tools ) 20 in Ducting | | Brand | AC Infinity | | Colour | 25 Feet | | Country of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (33,955) | | Item Dimensions L x W | 7.62L x 0.1W metres | | Item Length | 25 Feet | | Item Weight | 0.01 Ounces | | Manufacturer | AC Infinity | | Material | Aluminum Stainless Steel | | Maximum Pressure | 4 Bars | | Nominal Wall Thickness | Greater than single-layer thickness inches | | Number of Flutes | 1 | | Outside Diameter | 4 Inches | | UPC | 854759004952 | | Unit Count | 1.0 count | ## Product Details - **Brand:** AC Infinity - **Colour:** 25 Feet - **Item length:** 25 Feet - **Item weight:** 0.01 Ounces - **Material:** Aluminum Stainless Steel - **Maximum pressure:** 4 Bars - **Nominal wall thickness:** Greater than single-layer thickness inches - **Outside diameter:** 4 Inches - **Product dimensions:** 7.62L x 0.1W metres - **UPC:** 854759004952 ## Images ![AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection - Image 1](https://m.media-amazon.com/images/I/61gDYGO1+EL.jpg) ![AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection - Image 2](https://m.media-amazon.com/images/I/617bT01GrvL.jpg) ![AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection - Image 3](https://m.media-amazon.com/images/I/61sGtDyCAnL.jpg) ![AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection - Image 4](https://m.media-amazon.com/images/I/61laljY0z1L.jpg) ![AC Infinity 4-Inch Aluminum Ducting, 25-Feet Long Four-Layer Protection - Image 5](https://m.media-amazon.com/images/I/51RX5P0swZL.jpg) ## Available Options This product comes in different **Color, 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.
