32 vs 46 vs 68 vs UTF...which is highest viscosity

[NoPaint]

Between 32, 46, 68 hydraulic fluid and UTF...which one of these found fluids is the most viscous?

 

[RickB]

UTF is not a single oil but a category or collection of similar but not identical oils. Among AW32, AW46 and AW68 the AW68 has the higher viscosity. It would also be higher than most UTF oils.

The data sheets will tell you the viscosity, at more than one temperature too.
