There are 2 different types of lines.
My cooler fittings were different than the ones you showed,
would need an adapter like this, with the O-ring
Yep mine were the same style as yours, using the fittings that I suggest you in fact create the seal differently too how the original lines made their seal i.e on the inside. The seal gets created on the outside edge of the female fitting in the oil cooler. If you look carefully at the pics I posted you can just make out the O-Ring between the brass nut of the adapter fitting and the black aluminium nut on the cooler.

The one thing as I have mentioned in prior posts as linked to in my previous post in this thread is that you have to shave a bit of the fitting so that it screws in all the way so that the seal can get made.
