Gruntbear Portable Air Conditioner Window Seal Kit
Gruntbear’s Window Seal Kit is designed especially for casement windows, measuring 400cm (157″) to cover large openings. It installs easily between your window frame and the window, securing the air conditioner’s hose and effectively expelling hot air outside. The durable nylon material blocks hot air infiltration, enhancing your AC’s cooling performance and reducing energy consumption. Its waterproof function makes it reliable even during rainy days. This seal kit helps maintain a cool indoor temperature by keeping hot air out and cold air in, benefiting energy savings and comfort.
CHICHIBEBE 400cm Casement Window Seal for Portable AC
The CHICHIBEBE kit features an upgraded insulation with a 30% silver coating that reflects heat and adds waterproof protection. This double-layer silver-plated fabric blocks heat conduction and radiation efficiently, improving your portable AC’s cooling effect. The kit fits crank-out casement windows and is compatible with nearly all AC exhaust hoses up to 6.8 inches in diameter. Equipped with elastic sealing ropes and adhesive tape, it forms a tight, 100% sealed barrier to minimize heat reflux, lowering cooling costs and enabling fast room cooling.
Jyxmor 400CM Casement AC Window Vent Seal Kit
This Jyxmor window seal kit guarantees a 100% sealing effect, locking in cold air and preventing hot air from entering your home. Made from premium waterproof TU fabric, it resists rain and UV rays, protecting your indoor space from heat and moisture.

Easy installation combined with waterproof and UV-resistant technology ensures your room remains comfortably cool during hot weather.
Loviga Portable Air Conditioner Window Kit with Adjustable Fit
Loviga’s upgraded kit uses a drawstring design to create a snug, true zero-gap seal around exhaust hoses ranging from 1 to 6 inches, enhancing the barrier against hot air and outdoor elements like rain and bugs. Its waterproof TU fabric is treated with a heat-insulating whitening process to reflect sunlight efficiently. The adjustable length (40 to 64 inches) fits most horizontal or vertical sliding windows, providing an improved and more reliable sealing compared to zipper-type kits. Double stitched seams and wider Velcro tape ensure robust adhesion.
Kifiray Portable Air Conditioner Window Vent Kit for Sliding Windows

The special TU fabric is waterproof, UV-protected, and heat-resistant, preventing heat from seeping through while keeping out rain and insects. This kit offers a simple, reliable structure designed to enhance cooling performance and lower energy consumption effectively.
Buying Guide for Air Conditioner Awning and Window Seal Kits
Compatibility with Window Type
Confirm whether your window is a casement, sliding, crank-out, or awning style. Some kits specifically fit casement or sliding windows, so measuring your window’s width and opening style is critical before purchase.
Sealing Method
Kits use different sealing designs — zippers, drawstrings, or elastic cords. Drawstring and elastic seals generally provide better snugness and fewer gaps than zippers, reducing air leakage and improving efficiency.
Material Quality and Waterproofing
Look for durable, waterproof, and UV-resistant fabrics such as nylon or TU fabric. These materials withstand outdoor conditions, prevent moisture ingress, and block heat effectively, extending product life.
Adjustability and Size
Consider kits with adjustable length or width to fit your exact window dimensions. Kits offering sizes from 40 to over 150 inches accommodate various window sizes and portable AC exhausts.
Energy Efficiency Impact
Choosing a well-sealed window kit enhances your portable AC’s efficiency, lowering energy use by preventing hot air from entering your room. Some kits feature insulation coatings (e.g., silver) for better heat reflection.
Installation Ease and Durability
Opt for kits with simple installation mechanisms—Velcro strips, adhesive fasteners, or zip components—and sturdy materials for multi-season use. Easy removal and storage benefit users without permanent window modifications.
Extra Features
Some kits include rain guards or bird guards to keep outdoor debris and animals from entering through the exhaust hose. These additional protections improve usability when windows are left partially open for ventilation.
