        If the QC is an OEM Chinese one, I would never bother trying to repair it – the blasted things have too high a failure rate as it is, and Chinese rubber is notoriously bad.  Too many people have had the Chinese QC fittings on their loaders fail and deadhead the pump and blow it up. 

        Best to just replace the complete fitting with a good one from one of the quality brand name companies, I'd say.

          I managed
          to change the leaking seals. By using a small jeweler’s screwdriver I skewered
          the rubber O-ring and pulled it out. I did not remove the back up plastic seal.
          The size of the ring was 20mm x 3.5mm which I think is a R17 size. I was able
          to push a new O-ring into place using my fingers. If I ever decide to replace
          the complete coupling I would consider using the Flat Faced type. Apparently
          there is no oil loss when this type is connected and disconnected. All good
          now.

            Flat faces are nice. I changed all mine over when I got the skid steer, even the Prince pump.
