The yellow insulation is very brittle and itchy. Review: Good quality - 12 inch size. Just as good as any a/c hose I have ever used and priced well. Fit on the connectors easily. Don't judge my temporary installation, just keeping things cool during a remodel. If you roll a couple inches of the foil sheath back under as pictured it hides and contains the fiberglass that is very dusty and itchy. ## Features - Rubber - Compressible and easy to transport - Extremely cost effective insulated duct - Provides acoustical as well as thermal insulation - Insulation maintains temperature of air inside hose - Ideal for use for permanent and mobile air condition units ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N2IMR6W | | Best Sellers Rank | #67,946 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #89 in HVAC Ducting | | Brand Name | Rubber-Cal | | Color | 845605000000 | | Customer Reviews | 4.3 4.3 out of 5 stars (913) | | Global Trade Identification Number | 00845605070078 | | Included Components | Duct | | Item Dimensions L x W | 300"L x 6"W | | Item Length | 25 Feet | | Item Type Name | Duct | | Manufacturer | Rubber-Cal | | Material Type | Aluminum | | Nominal Wall Thickness | 0.02 | | Outside Diameter | 6.02 Inches | | UPC | 845605070078 | | Unit Count | 1 Count | ## Product Details - **Brand:** Rubber-Cal - **Color:** 845605000000 - **Item Length:** 25 Feet - **Manufacturer:** Rubber-Cal - **Material:** Aluminum - **Nominal Wall Thickness:** 0.02 - **Outside Diameter:** 6.02 Inches - **Product Dimensions:** 300"L x 6"W - **Specific Uses For Product:** AC ventilation, cold air supply, confined space ventilation, utility blowers, dehumidification - **UPC:** 845605070078 ## Images ![Rubber-Cal "HVAC Insulated-Flex" Ducting Ventilation Duct Hose, 6-Inch by 25-Feet - Image 1](https://m.media-amazon.com/images/I/71zC7HmIw4L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is it rated?
