The Lambro 3-inch by 25-foot flexible, semi-rigid aluminum duct (crimp-lock) is perfect for general HVAC venting needs, efficiently expelling air from homes. Suitable for HVAC systems, these ducts minimize air leakage and maximize performance, leading to substantial energy savings and enhanced indoor air quality. Ideal for new installations or replacements, the flexible duct resists collapse thanks to its corrugations, allowing for easy bending. Made from corrosion-resistant, non-combustible, and flame-resistant aluminum with a maximum operating temperature of 430F, it can be cut to length for optimal airflow. Manufactured from a dead soft aluminum strip, spirally wound and mechanically joined, it forms an airtight, leakproof seam. This self-supporting, corrosion-resistant product offers excellent strength and flexibility, adapting to low to high-pressure HVAC systems. The minimum bend radius is one diameter, but a 1 diameter radius is recommended. The aluminum ducting can be easily cut to size and shaped by hand.
