What pressure rating should a hydraulic fitting have?

 A hydraulic fitting's pressure rating should match or exceed the system's maximum operating pressure—including pressure spikes—with a safety margin typically set by a 4:1 minimum burst-to-working-pressure ratio, and it must also account for the fitting's size, thread type, material, and application duty cycle. Choosing a fitting on working pressure alone, without factoring in transient spikes and the manufacturer's safety factor,
