Making a Hard Line

[aktundra]

Making a hard line. The end there is a ridge to help keep the rubber hose from sliding back off. The rubber hose slips over it, and a hose clamp on the other side secures the connection

What is that ridge called, and what is the tool to make one on a new hard line?

I've heard them called hose beads or swages, and I think you can do them with a flaring tool if you know what you're doing. You can get specialized tooling to do it, but I think you need a die for the specific size you need.

I've not watched or used this video, but maybe it'll be useful? EDIT: Nevermind, that video is pretty janky. I'd bet Harbor Freight has something a little less home brewed if you don't need to do a bunch of it.
