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 feels very flimsy and theres such a draft. Its not much better than making one or of cardboard

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.

I bought a used portable air conditioner from my neighbor and the window vent unit was damaged. I purchased this as a replacement. It was a little large for my small basement window, but I was able to trim it and it fit well. I especially liked the way the exhaust piece easily snapped securely into the window piece. It was easy to remove and take apart when it was time to store the a/c unit.

Didnt notice that it had no hose so had to spend another 20 at home Depot for that and the hose was still too big.....good product just should include hose so your not having to find one

but the plastic is thin

I looked up Della Portable A/C and this popped up saying it would fit my A/C. It does not.

4 extensions in heavy-duty plastic, not thin. Connectors are easy to use and better than most that come with a portable a/c. Quality product.

Unfortunately the window kit shipped with our GE portable a/c was flimsy and cut in a way that the side panels blocked the hole to attach the hose in our size window (even though it said it could handle that window width). So we purchased this as a replacement, and it worked perfectly. It was easy to put together, its staying put, and its just generally doing what we need so we can run the a/c in the bedroom. Very happy with the purchase. Only recommendation is to seal around the edges with a high density foam tape (not typical weather stripping, but more like 1 1/4 in wide and 1/8 - 1/4 in thick.

take your time , it works well , this is the easiest way to vent air conditioner heat exhaust. I used a name brand tape to seal up with this kit, use the best tape that doesnt leave a sticky residue over time. So simple.

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
