Heating the threads with hot water or maybe a hairdrier will probably make them easier to unscrew, it works for me.

Is the system depressurized?

Have some wheatabix (blast from past)
And use your hands. You can get a good grip on them due to the nature of their design.
Yet i would also depressurized unit as well.
