WebDistance vs. Torque. Typically the procedure for tightening a compression fitting is specified using the rotation of the nut as the key metric, rather than torque. Compression nuts are threaded, meaning that the number of rotations of the nut is directly correlated to the linear compression of the ferrule, based on the thread’s pitch. WebThis also applies to mutual hard or soft joints in diff erent materials. Therefore, the torque wrench must be set to the proper value for each joint, depending on the desired torque. The torque should be determined in advance, using a transducer. 4. To ensure that the tool reaches the pre-set torque, the relevant joint requires an angle of at ...
