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

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.

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.

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.

The first kit I ordered arrived with a broken hose adapter ring. The product packaging is just a clear plastic sealed bag. The bagged kit came in the usual Amazon brown box which showed no signs of damage or abuse during shipping. The broken ring must have been damaged during pre boxing handling somewhere. The plastic hose ring is not protected against bumps or a dropped bag package.. The ring is thin sectioned, especially the circumference that goes through the hole in one of the door sealing plates. So I returned the whole kit and got a replacement. The second kit also came with a broken hose adapter ring. A piece was busted off about 2/3 of the circumference of the thin walled area of the ring. Strike two. Rather than return and replace with a third kit, I have glued the broken hose ring back together. Foolish because that may not be a reliable fix. But I do not believe this ring design is robust and even an undamaged ring it likely will need replacement after some use. Worst case… a broken ring could be held in place through the door seal plate using tape. I have not installed the kit yet (glue is drying) so no comment on function yet. I have fingers crossed the repaired ring is usable.

Seems to be good over all. I have my own insulation tape but woud have been nice to receive it.

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

The black foam sealing tape seals the gap pretty well.

works well wish came in smaller size for the vent hole, a 4inch hole would have been preferred but it was difficult finding one that had a 4 inch hole.

Was not sure how this would be but it was decent quality and easy to install. The window seal kit that came with the A/C was long gone and I needed a new one and this worked perfectly.

The concepts is simple and this product does in fact hold the exhaust vent in the sliding door… BUT when it comes with a broken hose connectors it renders this item useless!!!
