Right-Angle Adapters and Plug for Air Conditioner Exhaust

As shown, I have an air conditioner which has an exhaust hose which moves out hot air through the window and outside. I did a fairly good job weather-sealing it, and after some recent heavy rains, the weather-proofing has worked extremely well 🙂

I’ve been trying to look for a couple things, for which I have been unsuccessful.

First, it would be really nice to have a sort of "cap" or "plug" that I can use to close the port when the air conditioner tube is not connected. During the winter, I could attach the plug and move the air conditioner into the closet, freeing up some floor space.

Second, I’ve also been looking for a set of right-angle slim adapters to make it possible to put the air conditioner itself much closer to the wall. The hose currently doesn’t turn enough to make this possible.

I’ve tried searching with a lot of different terms. Do right angle adapters and plugs/caps exist, and what are they called?
