Pro tips for flawless installs:

Clamp the fitting body in aluminum vice jaws—never in bare steel jaws.
Use the adjustable spanner on the nut; tighten smoothly to seat the olive/ferrule.
Cut PTFE hose only after tightly taping the cut area to control braid fray; then remove the tape after cutting with quality shears.
Finish by pressure-testing the line before driving.
