When using two wrenches to tighten a fitting, how should the wrenches be positioned?

• A. Toward each other and pulled toward each other (one pushed and one pulled)
• B. One pushed and one pulled
• C. Away from each other while tightening
• D. Side by side and turned in the same direction

Answer: (A)

When tightening with two wrenches, you brace them so their handles move toward each other. This arrangement provides a solid reaction against the turning force, helping the nut rotate without letting the pipe or fitting twist. One wrench is used to push and the other to pull, creating the opposing forces that generate the tightening moment while keeping everything aligned. If you push the wrenches in the same direction or keep them apart and turn them the same way, there isn’t a proper reaction to resist the torque, which can lead to slipping, rounding the nut, or damaging threads.
