Shop Enerpac extended reaction arms for hydraulic torque wrench applications where the standard reaction arm cannot reach or properly engage a suitable reaction point. These accessories provide additional reach and help position the reaction point for specialized industrial bolting applications.
Select an extended reaction arm based on the compatible torque wrench model, required reach, application geometry, and available reaction surface. Proper reaction-arm selection is critical for safe and controlled torque application.
Choosing an Enerpac Extended Reaction Arm
Start by identifying the Enerpac torque wrench model being used and the location of the available reaction point. The extended reaction arm must be compatible with the wrench and provide appropriate contact with a strong, stable reaction surface.
Verify Torque Wrench Compatibility
Extended reaction arms are designed for specific torque wrench models and configurations. Confirm compatibility before installing the accessory.
Evaluate Reaction-Point Geometry
The reaction arm must contact a suitable stationary surface without creating excessive side loading or an unstable reaction condition. Additional reach should be used only when the standard reaction arm cannot provide proper engagement.
Confirm the Required Torque
The reaction arm and complete torque wrench system must be suitable for the torque required by the application. Accessory selection should consider both physical fit and operating load.
Applications for Extended Reaction Arms
Extended reaction arms are used in industrial bolting applications where surrounding equipment, flange geometry, structural components, or limited access prevents the standard reaction arm from reaching an appropriate reaction point.
Common applications include power generation, heavy machinery, process equipment, pipelines, industrial maintenance, construction, and large flange assemblies.
Complete Your Hydraulic Bolting System
Use an extended reaction arm with the correct Enerpac hydraulic torque wrench, industrial socket or drive accessory, torque wrench pump, and hydraulic hoses.

Enerpac Extended Reaction Arm FAQs
What is an extended reaction arm used for?
An extended reaction arm provides additional reach when a torque wrench's standard reaction arm cannot properly contact a suitable reaction point.
How do I choose the correct extended reaction arm?
Match the reaction arm to the specific torque wrench model and evaluate the reach and reaction-point geometry required for the application.
Can an extended reaction arm be used with any Enerpac torque wrench?
No. Extended reaction arms are designed for specific wrench models and configurations. Always verify compatibility before use.
Why is the reaction point important?
The reaction point absorbs the opposing force generated as the torque wrench turns the fastener. It must be strong, stable, and properly positioned to support controlled and safe tool operation.
