3 inch x 8 foot Flexible Aluminum Semi-Rigid HVAC Duct (Triple-Lock) – One Crimped End – Item #293F

The Lambro 3-inch by 8-foot flexible, semi-rigid aluminum duct is perfect for general HVAC venting needs, efficiently expelling air from homes. Ideal for HVAC systems, it minimizes air leakage and optimizes performance, leading to substantial energy savings and enhanced indoor air quality. Suitable for new installations or replacements, this flexible duct resists collapsing due to its corrugations and allows for easy bending. Made of corrosion-resistant, non-combustible, and flame-resistant aluminum with a maximum operating temperature of 430F, it can be cut to length for maximum airflow. A lightweight, non-insulated flexible duct, it features a triple lock seam created by spirally winding a dead soft aluminum strip, ensuring an airtight and leakproof seal. This self-supporting, corrosion-resistant product offers excellent strength and flexibility, adapting to any low-to-high pressure heating, ventilation, and air conditioning system.
