[AT] hyd cylinder different inlet threads?

[Len Rugen]

I'm pretty sure it's ORB, it's just they don't stock the fitting to fit the cylinder they sell.  The threads measure about 16mm outside, but I don't know how ORB are sized, I suspect it's ID, like pipe, but metric?  They are pretty fine too.

 I haven't seen the original post or know what era the hydraulic cylinder is but JD switched to the ORB type connection on their hydraulic cylinders when the New Generation tractors were introduced in 1961.

Probably O-Ring Boss.   ORB  You can get an adapter.  Take a look at 
Surplus Center's website, they have examples of the sizes. Discount 
hydraulic hose also does..
