The function of a hydraulic torque wrench is to convert hydraulic pressure into torque. This chart is a “quick-reference” to help in determining what this conversion factor is. If you do not find your torque and pressure values in the chart, then the following conversion formulas can be used to find your theoretical torque value. The actual value may vary due to wrench condition and age.
T = P x TF
P = T ÷ TF
Where:
T = target torque
P = pressure
TF = theoretical applied torque
