That's right. Make sure the first piece is set down tight and that the brass piece is all around the second piece.
Hope this works. Again, I would operate the machine with the front panel off so you can see exactly what is happening. Sometimes with a small leak you will want to wrap a piece of paper towel around the fitting so you can be sure and see it, a lot times it is to small to view.
Good luck and let us know how it turns out.
