A number 12 hydraulic fitting typically corresponds to a 3/4 inch size in terms of hose or tube diameter. The "12" in the fitting size generally refers to the dash size, which is a standard industry designation for the nominal size of the fitting. The fitting's actual dimensions, including thread size and outer diameter, may vary depending on the type of fitting (such as JIC, NPT, or BSP) and the manufacturer's specifications.
