【Universal Adjustable Size】This portable air conditioner sealing kit measures 10 x 40 to 64 inches (width) and fits all portable air conditioners and air dryers. It is only compatible with horizontal or vertical sliding windows (single or double sash).

【Improved Seal】Replaces the old zipper with a drawstring, allowing the sealing fabric to fit snugly over 1- to 6-inch exhaust hoses. This new air conditioner vent kit provides an excellent seal with a 0.1-inch gap, firmly trapping cool indoor air while preventing outside heat from flowing back in and keeping out rain, mosquitoes, etc. The special waterproof TU fabric is treated for thermal insulation and bleaching, effectively reflecting sunlight and providing rapid cooling, resulting in significant energy and cost savings. 【More Reliable Design】This window vent kit for air conditioners is designed to address the issues of inadequate sealing, zipper breakage, and easy zipper detachment, as well as complex installation. The design and structure have been simplified while improving product reliability. Furthermore, we use robust materials, double stitching, and widened Velcro and adhesive tape for optimal adhesion and sealing, ensuring maximum durability and practicality. 【Simplified Installation】1. Open the sliding window approximately 20 cm and stick the adhesive tape to the window frame. 2. Place the portable air conditioner window seal along the adhesive tape. 3. Extend the exhaust hose through the round hole. 4. Tighten the cord locking loop and secure the hose with the included Velcro to complete the installation. No drilling required, very simple.
