TORQUE LIMITS
INTRODUCTION
When To Use Torque Limits
When a torque is not specified in an individual work package, use the procedures in this work package to determine
proper torque limits and use of adaptors with torque wrenches.
How To Use Adaptors With Torque Wrenches
When 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 torque
wrench to the fitting being torqued, an equation must be used to compensate for the difference.
NOTE
The following abbreviations apply to the below procedures:
DT = Desired Torque
LT = Length of Torque Wrench
AL = Adaptor Length
AT = 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.

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:
