## Description

400CM (157") Portable AC Window Seal Kit

Review: Not easy to figure out how to use an ac unit in a window like this! We have an old house so these crank completely out. So both sides need to be sealed. It wasn’t difficult to install, just use the adhesive to apply all around the window frame and then velcro the plastic pieces together. It doesn’t look the most attractive from the outside but it’s better than dying of heat! There’s normally No leakage but if there is a heavy rain, the way it seals together on the top of the window creates a pocket… so it will start to get filled with water and can leak down the sides a bit. How to solve that is to raise it up making a pitch in the plastic so it drains off the sides so it won’t collect there. The zipper opens large enough to attach the hose through. It really is the best solution for this weird type of window. Ok, the only one! Haha
Review: Works very well, easy setup and great use out of it thus far. Keeps any bugs and birds out of my windows. Very soft fabric , white in color with mesh parts. There is no noise canceling to this but it definitely helped my finally install my AC to my weird apartment windows! I use it to install my Air Conditioner Hose for my apartment crank windows

## Features

- [Universal Fit for Multiple Window Types]: This window seal kit is compatible with various window styles, including casement, crank, push-out, and skylight windows. It fits windows with a maximum perimeter of 400CM (157 inches) and works perfectly with both single and dual-hose portable air conditioners of any brand or model. Perfect for windows that open inward or outward.
- [Flexible Zipper Design vs. Fixed Couplers]: Unlike rigid coupler designs that limit where your exhaust hose can be positioned, our flexible zipper system allows you to place your AC hose at any height. This solves the common problem of misalignment between your air conditioner and window, ensuring perfect compatibility regardless of your AC unit's height or window position. The adaptable zipper creates a perfect seal around exhaust hoses of different sizes.
- [Superior Cooling Efficiency & Energy Saving]: The AC window seal effectively prevents cool air from escaping and keeps hot air from re-entering your room, allowing your air conditioner to work more efficiently. By improving cooling performance and reducing energy consumption, it helps lower your electricity bills while ensuring a more comfortable indoor environment. Ideal for 12000 BTU and other high-capacity air conditioners.
- [Premium Waterproof & Weather-Resistant Material]: Made with high-quality, waterproof TU fabric with UV protection, this window vent kit prevents rainwater, dust, and other outdoor elements from entering. The durable construction ensures long-lasting performance in all weather conditions, providing a better cooling experience even during extreme summer heat.
- [Quick & Easy 5-Minute Installation]: No tools or drilling required! Simply clean the window frame, apply the strong adhesive Velcro strips to your window frame, attach the seal, and zip it around your exhaust hose. The adhesive leaves no residue upon removal, making it perfect for renters. Can be easily removed for cleaning or seasonal storage.

*by R***N on 3 July 2025*

The graphic on the ad implies there is a fixed form to insert two hoses. Actually it's just a series of zippers that lets you place the hoses in a convenient way. It does keep out moisture - as long as you make sure that the seal is tight on the tape side and the velcro side. Using the supplied zip ties helps to secure the zipper around the end of the hose, but self-sealing velcro tape wrapped around the end of the zipper to cover any opening helps to keeps insects out, and is less expensive to replace than zip ties. Reasonably priced, useful instructions and videos, likely to last several seasons.
