The threads on the cooler fittings don't strip upon removal. It only strips when the installing the cooler lines by force threading them.

What can happen upon removal is the fitting breaks free from the cooler when trying to loosen the lines. Try to get a wrench on both the cooler fitting and cooler line to prevent this. And PB blaster as Kerry noted.
