1. Adjustable SizeOur air conditioner seal comes in two sizes, approximately 300 cm and 400 cm, to fit your needs. It is suitable for all types of sliding windows (horizontal or vertical) and compatible with all air conditioners or air dryers. 2. Prevents Cool Air EscapeMade from specialized TU fabric for insulation and treated with a heatinsulating bleaching process, our seal effectively blocks cold air loss while reflecting sunlight and heat outward. This helps cool room temperatures quickly, saving energy and reducing costs. 3. Complete SealingThanks to its material and reinforced adhesive strips, our seal ensures a tight, gap installation. By preventing cold air leakage and keeping flies out, it provides protection. 4. Enhanced DetailsThe air conditioner seal features precise cutting and milling areas for easy adjustment without distortion. Additionally, the textured treatment near the outlet prevents the adhesive tape from falling off after inserting the air hose, eliminating potential gaps.
