Easy to install. The outer aluminum wrap is thin but doesn't rip easily. It's easy to cut using a razer. The insulation is decent. The clamps are no good though. The quality of the clamps is fine, but the screw takes a lot of effort to move. I ended up using large plastic zip ties instead of the clamps. Overall I'm happy with this purchase. Packaging was very good. Review: Simple if you know what you’re doing. - I recently purchased a home. After being in it for a year or so we’ve come to notice it was a flipped house. One thing we noticed is our upstairs was not cooling right in 2 of the bedrooms. Checked the vent and no pressure. Followed the hvac lines and someone thought it was a great idea to split a 6in into 2 rooms. Ran another line to the box with this flex duct and better flow, cooler rooms, happier hvac. ## Features - Efficient Insulation: Made with thick aluminum foil material and high-strength spiral steel wire, encased in a layer of fiberglass insulation, effectively reducing heat loss and improving thermal efficiency. - High-Quality Fiberglass Insulation: Reduces energy waste while absorbing noise generated during operation, enhancing comfort. - 3-Layer Tough: Constructed from durable aluminum foil and PET film, reinforced with a fiberglass grid, achieving an R-6.0 Thermal Resistance value, ensuring safety during operation and extending the product's lifespan. - Flexible and Easy to Use: Can be bent, compressed, or cut as needed for installation without affecting the interior of the duct, reducing air resistance and improving installation adaptability. - Variety of Applications: Primarily used for temperature control, dehumidification, and ventilation needs in various settings such as central air conditioning, fresh air systems, and greenhouse tents. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CS2MQCS8 | | Best Sellers Rank | #31,382 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #31 in HVAC Ducting | | Brand Name | VEVOR | | Color | Silver | | Customer Reviews | 4.5 4.5 out of 5 stars (216) | | Included Components | Flexible Duct x 1, Stainless Steel Clamps x 2 | | Item Dimensions L x W | 300"L x 4.2"W | | Item Length | 300 Inches | | Item Type Name | Insulated Flexible Duct | | Item Weight | 7.05 Pounds | | Manufacturer | VEVOR | | Material Type | Aluminum, Fiberglass, Polyester, Spring Steel | | Nominal Wall Thickness | 0.98 inches | | Outside Diameter | 4 Inches | | UPC | 197988275282 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** VEVOR - **Color:** Silver - **Item Length:** 300 Inches - **Item Weight:** 7.05 Pounds - **Manufacturer:** VEVOR - **Material:** Aluminum, Fiberglass, Polyester, Spring Steel - **Nominal Wall Thickness:** 0.98 inches - **Outside Diameter:** 4 Inches - **Product Dimensions:** 300"L x 4.2"W - **UPC:** 197988275282 ## Images ![VEVOR Insulated Flexible Duct 4" x 25 Ft R-6.0，Energy-Efficient 3-Layer HVAC Hose with 2 Clamps for HVAC & Exhaust Ductwork - Image 1](https://m.media-amazon.com/images/I/81uREoa7FjL.jpg) ![VEVOR Insulated Flexible Duct 4" x 25 Ft R-6.0，Energy-Efficient 3-Layer HVAC Hose with 2 Clamps for HVAC & Exhaust Ductwork - Image 2](https://m.media-amazon.com/images/I/818OLoAq3SL.jpg) ![VEVOR Insulated Flexible Duct 4" x 25 Ft R-6.0，Energy-Efficient 3-Layer HVAC Hose with 2 Clamps for HVAC & Exhaust Ductwork - Image 3](https://m.media-amazon.com/images/I/81RGauK1kfL.jpg) ![VEVOR Insulated Flexible Duct 4" x 25 Ft R-6.0，Energy-Efficient 3-Layer HVAC Hose with 2 Clamps for HVAC & Exhaust Ductwork - Image 4](https://m.media-amazon.com/images/I/81hy2vp19qL.jpg) ![VEVOR Insulated Flexible Duct 4" x 25 Ft R-6.0，Energy-Efficient 3-Layer HVAC Hose with 2 Clamps for HVAC & Exhaust Ductwork - Image 5](https://m.media-amazon.com/images/I/711KU7YOpML.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works good - clamps aren't good though *by D***E on December 21, 2025* This flex duct works good.
