Compression fittings
Those fittings (The common brass "short nut" fittings) don't belong on automobiles PERIOD. I would not use them on either brake or fuel lines. There is no vibration resistance. Only exception is the smaller 1/8 oil pressure line which is inherently stronger because the line is smaller
There exists (used to) AIR BRAKE compression fittings, which used more robust ferrules and long nuts resembling flare nuts. These are/ were far superior. They were also used on the nylon brake tubing which is OD sized same as copper/ aluminum tube
Also notice the other type air brake fittings have an internal ferrule to support the ID of the tube from collapse because of the ferrule
There also exists STEEL compressin fittings which can be used on such things as power steering repairs. You cut off the old hose from the formed steel tube ends, crimp up a hydraulic hose with these type compression fittings, and then put them onto the steel tube ends
The common ones I was familiar with "back then" were for dual braid hydraulic hose, came in straight and 90
