5.9 inch Portable Air Conditioner Exhaust Hose Coupler Window Adapter A/C Connector, Portable AC Hose Connector, Suit for Air Conditioning Exhaust Port (Square)

As you can tell from my picture, the duct tape residue is all over the exhaust pipe. I had no coupling for this LG model, only duct tape to attach the exhaust pipe to the machine. A genuine LG replacement is $60. This after market fits properly, no gaps. Very satisfied. Good value, easy to attach, just as good quality as the original part.

It is very good, I recommend it to several of my friends, they have already bought it, very good.

It didn't fit my unit

It worked as intended and it fit perfectly

Fit my portable ac hose perfect attached to unit just like original. Good quality.

Sturdy plastic grey in color. Odd, it was significantly larger than would properly fit my Midea. The rear circular opening was too small for the Midea vent hose. Everything fit with the help of duct tape.

with a little modification it fits as described.

Worked on an older Friedrich Portable air conditioner that was missing some parts. It didn't exactly screw in, I had to snap it in, but once in it worked great.
