Gates Pro Series hydraulic hoses are basic primitive products that get the job done for less. We could have published a Gates Digital Artwork Image of the Gates ProFlex hose, but that would not represent what you are actually buying.

This is an all black hydraulic hose with a white generic layline on the cover.  The text on this hose is very small and visually hard to read.

Both hoses have identical hose pressures and outside diameters.

The only difference is the published SAE and ISO requirements / ratings.

Those differences serve no purpose to the typical hydraulic hose consumers.
