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

The product was perfectly packaged in carton box but was damaged inside. Still works fine but I’m disappointed. Sellers quality standards below my expectations.

This is very easy to assemble & use. Great price.

I bought this after moving to an apartment where the best place for my AC is the sliding glass door. I refused to believe the question/answer part here that said you couldn’t open the door with this installed. Surely, there’s a way. I was right! It’s really not even hard. Just make sure you set it up to realllly fit, vertically, and it’ll stay no problem. I had the issue of a bit of a crack where hot air got in, and fixed it with the weatherstripping it came with + I bought a bit more to make it perfect. It stays just fine when I open and close the sliding glass door! Even better than that, I can still close and lock the screen door because it’s behind the vent. 10/10 great product.

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.

but the plastic is thin

quick and easy to set up and install (took just about as long as it does in the video). Its thick PVC and seems to be doing the job.

Pretty sturdy and easy to set up. I needed a wider extension because my window was too wide for the factory portable ac unit window attachment. It was perfect in size and more if needed. The foam seal roll that came with it is also a plus. Great product does the job.

Big gaps on the slider pieces even after applying foam roll. Probably going to have to do something like tape some bubble wrap on, which is unfortunate.

Packaging looks like this is a full kit with a hose. It is not. Im not sure why someone would want a window kit minus a hose, but now I have to shop for one of those as well, hoping it will fit this kit, because it is apparently completely impossible to find a full kit that is 5.1 and matches my unit. (The old hose and hose attachment have melted from so many summers of use).

Ordered the wrong size by mistake. It seems very sturdy and useful. Be careful while ordering. I had the right size but something happened in the Amazon app and I ordered the smaller one.
