Featuring a clear, abrasion-resistant thermoplastic body reinforced with a rigid yellow ABS helix, it offers exceptional durability and crush resistance. Its smooth interior ensures efficient airflow with minimal buildup, while its flexibility and wide temperature tolerance (-40Β°F to 200Β°F) make it ideal for professional-grade applications like lawn debris collection and industrial dust extraction. ## Description The Flexaust Flex-Tube PU polyurethane duct hose, used for dust control and light bulk material handling applications, is a clear, thermoplastic polyurethane hose, reinforced with a rigid external yellow ABS helix; it resists external abrasion, tearing, punctures, degradation by hydrolysis and microbes, and is flexible for easy manipulation. A temperature range of -40 to 200 degrees F makes it suitable for applications such as lawn and leaf collection. This duct hose is crush resistant, clear for viewing inside, and has a smooth interior to assure efficient air flow and the elimination of material build-up.Duct hoses are flexible or rigid tubes that convey gases, liquids, and lightweight bulk materials from one location to another. They are made from an array of materials that range from polyurethane and thermoplastic rubber, to PVC and aluminum-coated fiberglass fabric, and are typically reinforced with a steel wire or rigid plastic helix, also known as a β€œspiral.” Duct hoses are secured with hose clamps or U-bolts, and two pieces of hose are joined with a hose connector. Common applications for duct hoses include heating and cooling, ventilation, fume and smoke exhaust, vacuum cleaning, moving chips and shavings, handling bulk packing materials, and water and waste discharge.Flexaust manufactures flexible hose, metal ducting, and accessories for industrial and commercial applications. The company, founded in 1938 and headquartered in San Diego, CA, is part of the international Schauenburg Group. Review: Heavy Duty, High Quality - I purchased this 5" hose for my shop dust collection setup, and it is connected to my table saw. This stuff sees virtually no dust build-up on the inside thanks to the smooth walls, and the PU material seems to have a lot less static buildup than PVC and vinyl. It is very heavy duty and I can tell that it will take a real beating. This stuff is fairly stiff and heavy, which can make handling it cumbersome. I would not recommend using this in a tight space, or trying to store it in any sort of "compact" way because it is a little unwieldy. However, that's to be expected with a heavy duty item like this! I just fold mine in half and put it up against the wall behind my table saw when it is not in use. Initially I tried to store it up in the garage rafters, but that proved to be far too much of a hassle. Also note that the yellow spiral ribbing material will transfer yellow marks onto things if it is dragged over edges. The marks are easy enough to scrub off with a scouring pad, but just be aware of that. Review: Thick, heavy, will probably last forever, and nice color! - Very high quality, thick gauge hose. I use it for dust collection from my cyclone straight to each machine with adapter ports. The 6" size is very large and fairly stiff, so it won't be as flexible as other (cheaper) hoses. This may be good or bad for your desired application. I find it just flexible enough to move from one machine to the other. I prefer the heavier duty hose and the yellow color brightens up the shop. Can you get a cheaper 6" hose for the money? Absolutely... but if you want high quality and a nice look, look no further. The "smooth bore" interior is about as smooth as a flex hose can get. ## Features - Duct hose for dust control and light bulk material handling - Medium weight thermoplastic ether-based polyurethane is clear for monitoring flow, reinforced with a rigid external yellow ABS helix, and resistant to external abrasion, tearing, punctures, and degradation by hydrolysis and microbes - Flexible for handheld use and easy installation - Suitable for applications with temperatures up to 200 degrees F, such as lawn and leaf collection - Smooth interior assures efficient air flow and elimination of material build-up ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0050IIQM6 | | Best Sellers Rank | #1,385,221 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #136 in Industrial Duct Hoses | | Brand | Flexaust | | Brand Name | Flexaust | | Color | Clear | | Customer Reviews | 4.7 out of 5 stars 24 Reviews | | Item Dimensions L x W | 300"L x 4"W | | Manufacturer | Flexaust | | Material | Polyurethane | | Material Type | Polyurethane | | Maximum Pressure | 28 Pound per Square Inch | | Nominal Wall Thickness | 0.033 inch | | Outside Diameter | 4.07 Inches | | Product Dimensions | 300"L x 4"W | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Flexaust - **Material:** Polyurethane - **Color:** Clear - **Product Dimensions:** 300"L x 4"W - **Maximum Pressure:** 28 Pound per Square Inch - **Nominal Wall Thickness:** 0.033 inch - **Outside Diameter:** 4.07 Inches - **Manufacturer:** Flexaust ## Images ![Flex-Tube PU Polyurethane Duct Hose, Clear, 4" ID, 0.033" Wall, 25' Length - Image 1](https://m.media-amazon.com/images/I/71ykLlZ4M8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Heavy Duty, High Quality *by T***Y on August 31, 2015* I purchased this 5" hose for my shop dust collection setup, and it is connected to my table saw.
