Its steel-wire spiral core ensures superior flexibility and easy installation in confined spaces, while included stainless steel clamps guarantee secure, leak-resistant connections. Ideal for HVAC, dryers, grow rooms, and more, this ducting delivers reliable airflow management with customizable length and enhanced durability. ## Description From the manufacturer Product Description This ducting is designed for various ventilation, circulation, and heating/cooling transfer applications. It features four-layer protection, making it more durable and resistant to leaks than single-layer designs. The internal layer is made of heavy-duty dual aluminum foil that is fire/flame resistant. Its outer layer utilizes dual PVC thermoplastic that protects the aluminum from cuts and tears while stopping leakage. Each duct tube is held together by an internal steel-wire spiral that is flexible and easy to install in hard to reach places. The ducting can be shortened by cutting the tube to fit various applications. Includes two stainless steel duct clamps. Applications Primarily used with duct fan systems in various air circulation and ventilation projects including hydroponic grow rooms and tents, bathrooms and attics, heating and cooling transportation, and other installations. It is also used to cool AV equipment rooms, closets, racks, and cabinets. Aluminum Ducting Flexible ducting tube designed to route airflow in home HVAC applications. Creates a passage to supply, return, and exhaust air. The Most Essential Ventilation Accessory Ducting tubes are a vital part of any room that requires a regular exchange of air, facilitating air delivery for proper ventilation. Using ducting will streamline the airflow, ensuring good indoor air quality and thermal comfort in your home or workplace. Multi-layer Construction Features dual layer protection made of an outer thermoplastic and an inner aluminum. Employs a four-layer design that resists leaks, tears, and cuts. The spiral wire holds the tubular shape, while the inner lining stays smooth and straight when stretched out, maximizing airflow and diminishing CFM loss. Wire Coil Structure Makes installation easy by bending the aluminum duct tube in any direction. This allows you to accommodate most space restrictions. Steel Duct Clamps This set includes two steel duct clamps that secure the aluminum tubing to your inline fan or other duct openings. Fastens the loop using a Phillips screw. 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. - 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: 8 feet | Includes two stainless steel 4" duct clamps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WRDTX4C | | Best Sellers Rank | 12,773 in DIY & Tools ( See Top 100 in DIY & Tools ) 36 in Ducting | | Brand | AC Infinity | | Colour | 8 Feet | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 34,180 Reviews | | Global Trade Identification Number | 00819137021020 | | Item Dimensions L x W | 2.44L x 0.1W metres | | Item Length | 8 Feet | | Item Weight | 0.48 Kilograms | | Item weight | 0.48 Kilograms | | Manufacturer | AC Infinity | | Material | Aluminium , Stainless Steel , Thermoplastic | | Maximum Pressure | 4 Bars | | Maximum pressure | 4 Bars | | Nominal Wall Thickness | 1 millimeters | | Outside Diameter | 4 Inches | | Product dimensions | 2.44L x 0.1W metres | | UPC | 819137021020 | | Unit Count | 1.0 count | ## Product Details - **Brand:** AC Infinity - **Colour:** Black / Black - **Item length:** 8 Feet - **Item weight:** 0.48 Kilograms - **Material:** Aluminium - **Maximum pressure:** 4 Bars - **Nominal wall thickness:** 1 millimeters - **Outside diameter:** 4 Inches - **Product dimensions:** 2.44L x 0.1W metres - **UPC:** 819137021020 ## Images ![AC Infinity Flexible 100mm Aluminum Ducting, Heavy-Duty Four-Layer Protection, 2.4m Long for Heating Cooling Ventilation and Exhaust, 4" Ducting, 8 ft.

If there is a 4" circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole. **Q: anyone use this for garage auto exhaust tube?** A: I am currently using this to exhaust the air in my wood shop **Q: Is this suitable for marine use?** A: No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement). If you want to use it as a duct for a bilge blower, I would say go ahead and use it. If you are concerned about fire retardancy, I suggest you contact the seller first. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Proper stuff, sorted my dryer out! *by S***T on 2 June 2025* Finally got round to replacing the rubbish old ducting on me tumble dryer, the old one was practically made of cobwebs and hope.
