What are these in my car?

My car is a 1996 Honda Civic ex and there's two tubings with a blue cap sorry it wouldn't let me post a picture and I was thinks it was my a/c tubes but I don't know which one is which

The wider tube is the low side of the system.

One of the caps could be the charging port for the A/C. Does it look like a bicycle-tire air fitting under the cap? That's a freon charging port.
