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

Just what i been looking for every other kit i bought or came with my portable air conditioners are either huge and super long and require a saw …this fits perfectly with my weird size window and no saw was needed

Great adjustment and set up!

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.

Love it

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.

The hose hole is too close to the edge making a really bad angle when the kit is in the window - the foam provided is not enough to rectify for my windows. Also, I have a 34 inch window and had to cut the extended plastic in order for it to fit - all of the pieces shouldnt have been the same size! Definitely would not recommend due to the numerous hassles even though its a good price.

The vent kit that originally came with my Frigidaire portable unit was pretty bizarre, and was too large to fit in my pretty standard size upstairs window. I ended up accidentally breaking it try to make it fit. This was an incredibly simple fix that worked well that I should have bought months sooner.

The original kit that came with my air conditioner was way too short to fit my window. Apparently air conditioner manufacturers think no window should be more than 2 ft tall. Works great, remains stable, and is a decent price.

easy to assemble, sturdy and affordable!

Not sturdy when put together and installed. There’s no way to strengthen it. Waste of money if you’re using it in sliding glass door.
