The problem with that is two fold.Haha, brutal, it seems like at times parts can be a real crap show. Have you tried Applied? Used to be Bearings and Transmission? I just bought a couple o-rings from them, they had drawers full of all different sizes
First all orings aren't created equal and second to match them is only as good as your parts men and lots of them are completely incompetent.
For something like these valves I prefer parts from either Versatile or bosch rexroth themselves because you know you have the right size and quality needed.
Not some will fit oring that looks the same but might not be the correct material or harness.
