I use less than 2 wraps of masking tape (more than 1 and less than 2) and cut the hose with a cutoff wheel. I do not remove the tape before I put the ferrule on. I twist the ferrule only in one direction, usually clockwise looking at the end of the hose. The masking tape does not affect the joint so you can leave it on if you want. I oil the end of the hose to insert the fitting.

Duct tape is too thick to slip the ferrule over.

The thin cutoff wheels throw a lot of stainless hose debris so wear safety glasses and a face shield.....otherwise you will have stainless wiskers.
