Leaky Loader quick connect DK50se

[liberty2701]

The loader hydraulic quick connect has a persistent drip. Is there an o ring that I can replace or do I need to replace both male and female ends? I flushed out the fitting thinking some dirt got in there. It still leaks. It looks different than most 1/2" fittings I have used. Like the ones I purchased from TSC. Pioneer 1/2" ag.

Replace the 0 ring and see if it works most times it does.
