67 coronet power steering box

[D1esel]

My steering box is leaking fluid at the male inverted flare pressure fitting at the control valve. It is the fitting rhat the pressure hose screws onto. I believe there is an oring to seal between the fitting and the valve but I tried to unscrew the fitting but it was very tight and I did not want to break anything. Any ideas,comments,suggestions,please?

If you want a temp fix until you can get it apart, this stuff works.
