Aeroquip Metric Global Fitting

For general-purpose low and medium pressure hydraulics, this Aeroquip fitting should do the trick. It's also got Dura-Kote plating to help fight off corrosion.

For hose sizing, it lines up with a -10 dash hose since the Hose Dash Size is listed as -10. It is a 1A Series crimp hose fitting, so it is meant to be used in a crimped hose assembly rather than a reusable style.

General purpose low and medium pressure hydraulic systems are exactly what this fitting is built around. It uses a BSPP female swivel end on one side and connects to a -10 dash size hose on the other, so it covers a pretty wide range of everyday hydraulic work. One thing worth knowing up front: if your application involves shock hazards, you'd want to look at the H277 or H435 hose options instead of running this in that kind of situation.
