AC refrigerant lines.

OK thanks - I suspected they were.

They are currently closed (clockwise) - I assume that's correct?

The caps cover the connections, that are used for a 're-gas / service'

They are just to stop dirt etc getting in to the connection, rather than valves. So as long as they are on, but not overly tight, then you're fine.

Thanks a lot.
