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

It took me 5 minutes to assemble once I found the video tutorial. I live in Florida and the humidity can make the heat unbearable. Once this thing was in the room cooled down so fast. Great value.

Simple to install works perfectly

Easy to install, we used it as exhaust vent for my sons 3d printer and with some adjustments after 4 months we are very happy

Great adjustment and set up!

If your window is somewhere roughly between 17 inch and 21 inch you will need to cut the back plate down to size as the circular duct attachment protrudes out the back. Pretty expensive for what it is but then it appears they all are.

Its not bad construction, but there are issues unsolved with this solution. First, the window is open meaning hot/cold outside air will hit the sliding window and be forced up behind the fixed window right into the room. Second, the channels do not block hot/cold air, either. The outside air hits the seal kit and passes unimpeded into the room. They could have solved that with a notch that fit into the channel ahead of the metal plate. Last, the sides of the kit are thin material making it impossible to secure the sealing foam and block air from passing around the kit. 3 flaws there. And, why did they send 5 sets of plate/screws?? The installation 5x7 is totally insufficient.

Doesnt seal at all or hold in any of the cold air your bringing in from fan I dont recommend it unless you are just wanting to keep the bugs outside by having window or slider mostly shut

bought as like new and only came with 1 extension and hole piece. EVERYTHING else was missing. Screws, seal, adapter and extensions.

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.

I have the black and decker portable AC, So The hose ring is too big for this kit, The slabs are a tad bigger than the slabs that come with the AC, I was able to use both kinds of slabs and conjoin them together to make it longer as I needed. I would say buy the hose and hope it has the right ring to fit together properly.
