The T-6B hydraulic system uses fluid pressurized to 3000 +/- 120 psi.

Explanation:
The hydraulic system in the T-6B is designed to deliver consistent force by maintaining fluid pressure around 3000 psi, with a tolerance of ±120 psi. This means normal operation is roughly 2880 to 3120 psi. That specified range accounts for variations in pump output, temperature effects on fluid viscosity, and minor leaks, while still providing reliable control authority for the flight surfaces and systems. The system uses a pump, an accumulator, and relief valves to regulate and stabilize pressure, ensuring actuators receive sufficient force during maneuvers and to avoid damage from overpressure.
