In the article they reference Seal 7, well I ordered some just to have them around and they are very thin caps that go over the male end of an AN fitting and act as an internal crush seal, they are a bit pricey but if you have a leak they appear to be a quick fix and the fact they were developed for NASA to use on rockets seems to backup the fact they work. Some of our aerospace members may have more experience with them than I. I am hoping not to have to use them but they will be my first move to try and stop any leaks if a slight tightening doesn't work.
