How To Use Adaptors With Torque WrenchesWhen an adaptor is necessary due to space or type of fitting being torqued, it must be determined how the adaptor changes the amount of force applied. If the adaptor increases or decreases the distance from the drive of the torquewrench to the fitting being torqued, an equation must be used to compensate for the difference. NOTEThe following abbreviations apply to the below procedures:DT = Desired TorqueLT = Length of Torque WrenchAL = Adaptor LengthAT = Applied Torque 1.If the adaptor used decreases the distance between the center of the torque wrench handle and the center of the drive, first find the desired torque for the fitting, then calculate as follows:a.Multiply DT by LT. b.Subtract AL from LT.c.Divide the first answer by the second answer to find AT.2.If the adaptor used increases the distance between the center of the torque wrench handle and the center of the drive, first find the desired torque for the fitting, then calculate as follows:ALLTWRENCHHANDLECENTERLINETORQUE WRENCHDRIVECENTERLINEADAPTORDRIVECENTERLINEALLTWRENCHHANDLECENTERLINETORQUE WRENCHDRIVECENTERLINEADAPTORDRIVECENTERLINE
