Will this fitting work on a standard hydraulic hose?

This Aeroquip fitting is made for a wide range of applications, so it should work with most hydraulic hoses. Just be sure the dash size (-4 in this case) matches your hose.

fitting's made of brass, right? just want to make sure before i order a handful of these for a job

Brass is correct. The 412-2-4B is a brass fitting, which makes it a solid pick where corrosion resistance matters and you're not dealing with extreme heat or aggressive fluids that would rule brass out.
