Kanaflex® 660YD Heavy-Duty Ducting Hose is built for rigorous applications requiring durability, visibility, and abrasion resistance. With a smooth EPDM rubber bore for efficient airflow and a "safety yellow" polyethylene helix, it ensures superior abrasion resistance, making it ideal for dragging applications. The 100% rubber sidewall provides enhanced durability, while its smooth interior and corrugated exterior support flexible handling. Rated at 4 PSI and withstanding temperatures from -40°F to 140°F, this hose is perfect for duct cleaning, commercial leaf and grass collection, cement dust recovery, and grain auger downspouts.
