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 understood that there were two size exhaust hose diameters, 5.1” and 5.9” I ordered, by mistake, and returned the 5.1” This one was the 5.9” which is what I thought was the right size but my exhaust hose didnt fit in the outlet connector. Not did the outlet connector already on my exhaust hose fit in the new panel’s hole. I had to modify the panel with the hole that I already had (by drilling a new hole for the connection hardware) so I could integrate my existing panel to fit with the new ones. It was an easy adjustment but I dont know why my hose didnt fit into the new parts. Could be user error but unless there is a 6” exhaust hose rather than the 5.9” it makes no sense. Otherwise product is great and works well. Measure carefully!

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.

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.

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

I should have listened to the other reviews. The gasket fits (screws) securely onto the hose, that’s no problem, but it will not stay on the part that goes in the window. Part of the problem is the plastic parts that stick out and are supposed to function like like a latch are barely more than a bump and won’t catch. Another problem is the clearance for the window frame is not tall enough so the hose rests on it and bumped out of the slot.

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).

No issues.

I find that I have to adjust mine regularly to keep it the right length to fit my sliding door. Also the weather stripping was to short to cover both sides.

EZ as pie to install .

Perfect
