To determine the size of a hydraulic fitting, measure the outside diameter of the threads using a caliper and count the number of threads per inch (TPI) for a male fitting, or measure the inside diameter for a female fitting. Additionally, consult the fitting's specifications or use a thread identification gauge to match these measurements to the appropriate fitting size standard, such as NPT, BSP, or JIC.
