Farmall 460 hydraulic supply hose

Does anyone know the thread size for the hydraulic supply hose where it threads into the hydraulic block? I'm looking to plumb some remote valves in series with the original valves to run a loader. Any thoughts? I do not have power beyond valves.

I don't know the size but it is straight thread, not tapered pipe so you can measure the outside of thread to determine size. On putting a valve in series there, be certain it has a relief valve of it's own and approx 1500 psi. Not really a recommended way of plumbing that system.

Most likely its a 1-1/16 orb male thread, next size up would be 1-3/16 orb. They are SAE hyd fittings, IH used them a lot.

Pretty much what I said as ORB (0 ring boss) is merely a groove for an o-ring on a straight thread. I was at service training session in 1959 when IH first introduced this style of hydraulic connection on hydraulic cylinders etc although they had been using them some on the older models on hydraulic valves etc.
