Pressure versus Torque HMT-Series Torque Wrenches

The function of a hydraulic Torque Wrench, is to convert hydraulic pressure into torque. This chart is a “quickreference” 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 T_F

P= T / T_F

Where:
    T = target torque
    P = pressure
    T_F = theoretical applied torque
