DOT Fittings Question

When I need to take off an airline, and then reuse the fitting, with a Parker DOT fitting will the ring part be re-usable or will I have to buy another? Ive changed lines alot with ace/lowes cheap fittings and had to have spare rings/inserts.. but these Parker fittings, the Insert is built into the fitting and the ring has a small ring around itself im guessing to seal more properly. anyone know?

u should be able to reuse it
