Portable AC Window Seal with Universal Coupler, 100% Sealing Effect, Upgrade Waterproof Seal for Crank Out/Awning/Skylights Window

In the sweltering heat of summer, installing a portable air conditioner in a casement or crank window can be a frustrating task. To effectively vent your portable air conditioner and keep the cool air in while shutting out the hot summer air, the easiest solution is to use a portable air conditioner window seal kit.

If you don't want to drill a hole through the house wall or leave a window open, which can lead to issues like dead leaves or a sopping wet room from sudden showers, the Aozzy Portable Air Conditioner Window Seal is the perfect choice. The window kit that comes with most portable air conditioners is designed for traditional sliding windows, but that doesn't mean you can't enjoy the clean look of a crank window and the cool comfort your new portable air conditioner provides.

While a portable air conditioner unit helps cool down your room, it can also leave your house vulnerable to unwanted guests if you don't secure the window with the vent installed. With your window open and the venting kit in place, you can no longer use the lock on the window. This is why it's strongly recommended to get a security window lock for your portable A/C unit, which will allow you to fasten and lock your window despite the vent kit, reducing the likelihood of a break-in.

The Aozzy Portable Air Conditioner Window Seal Kit offers several key benefits:

【100% Sealing Effect】Compared to the old-fashioned zipper design, this new portable air conditioner window vent kit uses an external round interface that ensures excellent 100% sealing, perfectly fitting the hose interface and firmly blocking heat and rain. With two size options, it can effectively cool the air conditioning window and maintain a stable cool temperature for a long time, saving energy and money.

【Universal Compatibility】The Aozzy window seal, with a maximum perimeter of 400 CM (three sides of the window), is suitable for bottom-hung windows, skylights, and casement windows (except sliding windows). It's not only for portable mobile air conditioners but also for dryers, exhaust dryers, and dehumidifiers, allowing you to enjoy a cool and comfortable summer no matter what type of air conditioning unit you use.

【Easy to Install】No drilling or tools are required, making it a breeze to install. Simply wipe the window frame clean, stick the Velcro on the frame, attach the window seal along the Velcro, connect the exhaust pipe to the round connector, and connect the interface of the sealing cloth.

【Quality Materials】The window sealing cloth is made of nano polyester material with double stitching technology to enhance sealing, waterproofing, and heat insulation. The Velcro is thickened to 2cm to improve adhesion, with high-temperature resistance and no residue for disassembly. The external round connector features a skeletonized design.

With the Aozzy Portable Air Conditioner Window Seal Kit, you can enjoy a cool and comfortable summer while keeping your home secure and protected from the elements.
