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

Works prefect for the AC

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.

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

Fits well in sliding glass door track. Easy connection to existing exhaust hose. Much better alternative to the 2 x 4 piece of lumber I used to use to cover area above exhaust port.

Simple to install works perfectly

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

but the plastic is thin

Its really easy to use. The pins really help. If I ever need another one, I will definitely buy!
