For fit confirmation, this SPX nitrile O-ring is sized at 0.362 inch inner diameter with a 0.103 inch cross-section, which matches the -110 size called out.

Nitrile is the material here, and it's well suited for exactly that kind of exposure. Petroleum-based fluids like hydraulic oil are right in the wheelhouse of what nitrile handles well. It resists breakdown from oil and fuel, so you're not looking at premature swelling or deterioration under normal hydraulic operating conditions.
