Fleks 4" x 25' Vent Hose is engineered for demanding ventilation needs, handling unconditioned air with ease. Its triple-laminate construction and industrial-grade foil casting ensure durability under high heat, humidity, and airflow without fatigue or failure. The ultra-smooth, double-sealed core promotes silent, frictionless air movement, while rip-stop material prevents tearing. Galvanized spring steel maintains duct shape and resists rust, withstanding temperatures from -4°F to 175°F. Includes two clamps for secure installation, making it a reliable choice for professional ventilation systems.
