Burlete de sellado para ventilación de ventanas de aire acondicionado, 500 cm, impermeable

【Versatility】This portable air conditioner window seal is suitable for skylights, awnings, casement windows, and inward-opening or tilt-and-turn windows (excluding sliding windows or inward-opening/tilt-and-turn windows) as long as the window circumference is less than 500 cm. 【Sealing Effect】The innovative pull cord design ensures a perfect fit for 12.5 to 15 cm hoses. It achieves a "zero" seal without any additional accessories. It firmly locks in cool air while effectively blocking hot air, rain, and insects. Additionally, some zipper openings are included for connecting hoses of different sizes as needed. 【More Reliable Design】This portable air conditioner window seal is specially designed to avoid the shortcomings of zipper seals, such as gaps, tears, slippage, and complex installation, thus improving sealing and reliability. Furthermore, we use sturdy and durable materials, double stitching, and wider Velcro and tape to further enhance adhesion and sealing, making it truly durable and practical. 【Easier Installation】This portable air conditioner window seal features a simple design and is easy to install. No window kits, hose connectors, or extra tools are needed, and no drilling is required. Simply attach the Velcro to the window frame, apply the weatherstripping, and tighten the pull cord. 【Usage Tips】 1. Clean any dust from the window frame before applying. 2. For air conditioner window weatherstripping, apply the curved side to the outer frame and the straight side to the inner frame. 3. It is recommended to start applying from the center of the window frame.
