Thats how it should have been done from the start.
Perhaps with a little more thought and planning for hose routing, things could have been mounted a little different so it would be more "clean" looking and use fewer fittings. Perhaps not.
Ultimately you had to go from -10 ORB ports on the valve to -08 JIC on the tractor. And to 1/2" NPT for the remote couplers. There are dozens of was to accomplish this with various fittings, hose ends, and adapters.......as you have found out.
Really one way isnt any more correct than the other.
What matters is its correct now, and hopefully will solve your leaky valve issue.
