Interesting idea using ferrules as a small tube bead.
I stay far away from worm clamps on hoses smaller than 1". I use constant tension spring clamps and fuel injection clamps for smaller hoses.
I'm moving away from worm clamps to spring clamps on larger stuff like radiator hoses at this point. Toyota has been using them for a couple decades and they don't leak. I hate the locations the thoughtless line workers tend to put the ears at the factory, and I'm not the only one that does, but they can be moved to a location that's accessible so they work for fine the rest of the life of the vehicle.

Much agreed on the worm clamp avoidance when/where possible & I prefer the use of the FI style clamps. I haven't found a good local source for them in a high quality material & I have readily available access to SS worm gear hardware so it's more of a default thing.
