3 inch x 8 foot Flexible Aluminum Semi-Rigid HVAC Duct (Crimp-Lock) – One End Crimped

The Lambro 3-inch by 8-foot flexible, semi-rigid aluminum duct, crimped at one end, is perfect for general HVAC venting needs. Ideal for new installations or replacements, it ensures minimal air leakage and optimal performance, saving energy and enhancing indoor air quality. The duct's flexibility, thanks to its corrugations, prevents collapse and allows for easy bending. Made from corrosion-resistant, non-combustible, and flame-resistant aluminum, it operates up to 430F. During installation, it can be cut to length for maximum airflow. Manufactured from a 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, with a recommended radius of 1 diameters. It can be easily cut to size and shaped by hand.
