Universal Window Seal Kit for Portable Air Conditioner of Exhaust Hose 5.1 Inch Diameter with Coupler Adjustable AC Vent Kit PVC Seal for Sliding Window

I didnt use it vertically, I used it horizontally and it worked out great. It was easy to fit to size and I was able to connect it to my ac unit easily. It stops hot air from getting in and cold air from getting out. Mainly, it stopped the bugs.

No issues with this. Very pleased at its easy install.

It worked with my midea portable air conditioner

The plastic is super thin and flimsy. Not like the plastic that usually comes with AC units. Missing pieces. On top of that I selected the right size, but the adapters didn’t work for my AC even though it says it for that brand. Mostly my one star is just the quality itself. The foam that comes with it, is so thin hardly insulated. Horrible adhesive. Doesn’t even stick.

Use the window seal it comes with for the slider gap and just order thicker weather seal to go over border of window kit.

Fit in window and very easy install.

Easier than the original component.

The insert that came with the a/c was too short. This gave me the extra length I needed to fit the tall windows.

great set for window portable AC

Perfect
