... don't know exactly what your dealing with. I'm guessing your dealing with a compression fitting, if it was PEX, you couldn't tighten it. Compression fittings make an excellent seal without much tightening when equipped with cone washers. Cone washers are available at any hardware store.
I don't think you are at this point, but if I have a problem connection I replace the line with braided nylon hose and secure it with hose clamps. It's inexpensive and lasts for years.
