Quick Disconnect Drip

[Dennisfly]

I have a John Deere 855 with loader. I have never removed the loader. The quick disconnects for the loader are located under the left foot pan. After I shut the tractor down, it will drip from the area of the disconnects. Are there O rings or other seals that I can replace? If so, are they a standard size I could buy from the hardware store or a special John Deere size?
