The Novaflex® U-Lok 1500 is a heavy-duty, two-ply high temperature duct designed to handle the toughest industrial environments. Built with alumina-coated textile glass fabric reinforced by fine V4A wire, this duct offers superior durability and exceptional resistance to extreme heat—up to 1500°F (816°C) intermittent service. Its robust construction provides a longer service life, making it ideal for demanding applications such as hot air extraction, furnace construction, and use in iron and steel works. The galvanized steel helix and mechanical bond ensure structural integrity, while its 4:1 compression ratio allows for easier handling and storage. With reliability and performance engineered into every foot, the U-Lok 1500 is the duct you can trust for high-temperature air movement. Note: A negative pressure fan system with ambient air inlet is recommended to maximize effectiveness and life of duct. It is important to size the hose diameter according to the exhaust output.
