Hydraulic leak @ quickattach

[mefyj]

I have a hydraulic leak at the quickattach. Would like to know the size of the tractor end. It's behind the metal holder and I can't get a regular wrench on this so I'll have to get a flair wrench to fit it. But want to be certain to get the correct size. Likely just need some tightening.
