It's probably designed to be hard to put on so it doesn't come apart easy, that thin band of blue is probably nylon. It helps lock the nut in place.
You should be able to hand tighten a few turns, after that you'll need wrenches. There should be some resistance but not an overwhelming resistance.
If you have some pictures that would help.
