JD remote hydraulic leak.

I have replaced the o-rings in both sets of remotes on my 2640 with aftermarket o-rings and they don't appear to leak until I hook up to a remote cylinder and turn them on. Then alot of hydraulic fluid flows out the bottom of the break away coupler unit. Right at the bottom of the vertical shaft used to turn the pressure on. I used 2-3 gallons planting half acre of sweet corn today. Could it be that the units are shot or could the o-rings be bad still or just the wrong ones? I fear JD is going to want alot for the rebuild kit, about $80 per side which, I believe is no more than about $1 worth of o-rings. Should I consider changing from the stock John Deere breakaway couplers to something else. Has anyone else had this problem before and if so what did you do to handle it? Thanks, I could really use the help.

I either have to stop the leaking or find hydraulic fluid that is high in nitrogen and leave it as is for side dressing.
