That does indeed look close. But the text calls them low pressure applications the hose in the picture I put up was from the power steering box (high Preasure)

But the picture you showed looks exactly like the ones on my transmission cooling lines. Slightly different but will possibly work. In fact I was about to see if I can connect my transmission fitting to my PS box. But who knows they may only consider that fitting low pressure because of it having a barbed fitting on the other end.

I couldent find wher you got the name "Ball Swivel/Metric", but they did mention NPSM.

I have also found similare fittings to this.

DIN L or S ball nose series or DIN 60° Cone. Or BSP, JIS 60° Cone.

One of the problems I'm having is any pictures I get on the web show the fittings with the nuts extended over the flare or cone. The cone fittings mentioned above do appear to be more of a machined finnished tapered cone. Compared to the more spherical specimen I showed in the picture.

I may just have to order a few specimens of each and see which looks best,but I really need the ends that get silver soldered to the steel tube and preferably in stainless.
