Enerpac RSL-Series, Hydraulic Torque Wrenches, Hex Cassette or Square Drive Head

How to Choose an Enerpac RSL Hydraulic Torque Wrench

Match the wrench to the joint before you order. The factors below drive the selection:

• Torque range (ft-lb): Confirm the target torque for your bolt grade and size, and pick a wrench whose rated range brackets that value rather than running at the extreme end.
• Drive style and size: Hex cassette heads engage the nut or bolt flats directly in tight clearances; square drive heads accept standard impact sockets. Verify the across-flats hex size or the square drive size you need.
• Operating pressure: RSL tools typically run on a 10,000 PSI (700 bar) hydraulic circuit; confirm your pump and hose are rated to match.
• Reaction arm and clearance: Check that a reaction point is available within reach of the tool and that the reaction arm seats squarely against an adjacent nut, flange, or fixed surface.

Which Enerpac Torque Wrench Is Right for the Job?

The RSL cassette-style wrench is built for low-clearance and limited-access joints where a full square drive housing will not fit. If your application calls for a dedicated square drive tool with standard impact sockets, compare the Enerpac RSQ-Series Torque Wrenches and Square Drive Heads. For higher torque output or a different head configuration, review the Enerpac HMT-Series Hydraulic Torque Wrenches, or browse the full range of High Pressure Bolting Tools to weigh torque, clearance, and drive style side by side.

Complete the System

An RSL wrench needs a matched power and reaction setup. Pair it with a 10,000 PSI Hydraulic Pumps source and rated Hydraulic Hoses to drive the tool. For reach and reaction in awkward joints, add the Enerpac ERT-Series, Extended Reaction Tube for RSL Torque Wrenches and the Enerpac RRA-Series, Reaction Arm for RSL Torque Wrenches. Stock Torque Wrench Accessories and keep Hydraulic Nut Cutters on hand for seized fasteners you cannot break loose.

Cross-Referencing an Obsolete Enerpac RSL Wrench

If you are working from an Enerpac model number that is no longer cataloged, or you need a head or cassette to match a wrench already in your kit, we can usually identify the current equivalent from the torque range, drive size, and head type. Supplying us since 1963, we have the manufacturer reference data to cross from a discontinued part to an in-stock replacement. Send the model number stamped on the tool, the torque you need, and the bolt size, and we will request a cross-reference.
