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

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.

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.

I bought a very expensive Frigidaire portable AC and it came with a flimsy cheap window kit. This is as sturdy as metal....maybe it is....and took no tools or tape to work correctly. This is what should have been included in the $550 the portable AC cost. And BTW, 5.9 is the same as 6 when it comes to the hoses on these portable units. So Frigidaire says its 6, they really mean 5.9.

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

great set for window portable AC

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.

No issues.

It all seems nice upon unpacking, and packaging is great (suggesting a quality product) but the joy is of short duration! Once mounted, there are huge air gaps everywhere, top, bottom, sides and in-between, and the door lock mechanism has absolutely not been taken into consideration, adding to the gap. Insulation = zero, no matter how much of the provided tape you intend to put up. The hose adapter that clicks into the frame is totally non-sealed, and loose-ish (air gaps). Regretfully, I only unpacked it now, as I have not used it last year, unfortunately!!!, otherwise it would have been a straight return!!! Very very upset with this purchase.

Item is just what I wanted. Good quality for the price.

It fit perfectly.
