A while ago I saw this "special" tool on Youtube and I thought it was really
good for those who do their own automotive plumbing. To form a bead that prevents the hose from slipping off they showed a crimping tool that is slightly modified. I ordered one from Ali-Express for a mere $12 and then I cut the nose of the one jaw off with an angle grinder, remove the ratchet mechanism and see there, you have a "crox" tool to do any diameters.
