1. Adjustable size: Choose between two sizes, approx. 300 cm and approx. 400 cm to adjust the length of our air conditioning seal according to your needs. This seal fits all types of sliding windows (horizontal or vertical) and is compatible with all portable air conditioners or air dryers. 2. Prevents air leakage: Made of special TU fabric and treated with a heatinsulating bleaching process, our seal effectively blocks the loss of cold air while reflecting sunlight and heat outwards. It helps cool down the room temperature quickly, reducing energy waste and cost. 3. Complete sealing: Our air conditioning seal ensures a tight and gap installation thanks to its material and the extended fixed sticker. It not only prevents cold air from escaping but also keeps flies and other pests away, providing excellent protection. 4. Upgraded Details: With precise cutting and milling areas, our air conditioning seal allows for easy adjustment without distortion. The texture treatment near the outlet prevents the tape from falling off after inserting the air hose, ensuring a seamless, gap seal.
