The ATS Parker Beading Tools are darn nice but the price is pretty dear. Here they are FWIW
I have seen similar bead forming tools made from modified pipe cutters. Depends on your tooling availability and skill set.

The Earls tube beading tools work fine for a few tubes.

Many of us use steel tubing for various lines. Not sure if that EZ Beader does just aluminum or if it can do steel as well.

For the part-time/shade-tree builders, brass compression fittings also work as an easy way to get it done on steel tubing w/o a bead forming tool. Put a ferrule + the male/female portions of a brass fitting together on the tube. Tighten the male/female portions to locate & 'crimp' the ferrule in place. Loosen the male/female portions. Then grind/cut the female portion off as needed using an angle grinder.

The crimped ferrule is left on the tube & the hose can be forced over it w/a single worm gear clamp to keep it firmly in place.
