Torque wrench's come in many shapes, sizes and styles ranging from the basic beam, clicker wrench or even electronic wrench. In 65-70% of gasket failures, the main cause of the failure is linked to under loaded gaskets. Applying the correct torque helps ensure that you are properly stretching the bolts, which in turn act like a spring pulling the flanges together, creating load on the gasket and achieving an effective seal. Torque wrenches can range in price and accuracy, however, despite the tool’s price tag, a torque wrench is only as good as its last calibration. So be sure to do this before putting it to use.
