I'm not sure I correctly understood what you mean. But if I do, yes, we can make any kind of flexible hose with crimped fittings (no olive, but a crimped collar, non-reusable fittings).

The only problem is that they need to be "factory made" as you need a special (and expensive) machine to crimp the collars. So they need to be ordered at the right length from the beginning. The big advantage of reusable (olive) fittings, is that you can assemble the brake lines directly on the car. We also do a lot of reusable fitting lines (we have a full range of reusable fittings too), but mostly for racing cars and motorbike.

My entire brake line circuit is made of flexible lines. The flexi lines from callipers to chassis bulkhead have crimped fittings too... if it was your question

Yes, that is a good guide of how to fit a reusable (olive) fitting. I would use a crossed beak cutter rather than a hack saw to cut the hose though . But that is the way you can do it at home.

I'm not sure about Sweden (I haven't checked because I will not install brake lines with reusable fittings on my Roadster) but in France, brake lines with olive fittings (reusable) might fail "contrôle technique" (equivalent of your MOT visit), because it is not sure they have been professionally made, or fittings could have been undone and badly reassembled without being able for the inspector to check. So crimped fitting brake lines are more adapted to road vehicles, and reusable fittings to racing vehicles.

But again, I hope I correctly understood your question
