On ya Nick!! Back to the plot - Use the correct socket or a good ring spanner. Work on it cold. Try to TIGHTEN IT SLIGHTLY first and then remove. I'm amazed the pipe has not torn open with the force you say you are using. If possible soak with your favourite penitrant over night (cold) before having another go.
Good - Fast - Cheap: Pick any two.
