Square Drive and Low Profile Hydraulic Torque Wrenches.

Maximum Torque at 690 bar:

1909 - 37.965 Nm

Hexagon Range:

26 - 155 mm

Maximum Operating Pressure:

690 bar


Our new RSL-Series Low Profile and Square Drive Hydraulic Torque Wrenches provide a simple and robust solution for bolting applications. The drive unit is equipped to operate both the square drive head and the low profile hexagon cassette for usage in tight spaces. The “one drive, two tools” design lets users quickly change between tools during operations, enhancing productivity and lowering tool investment costs.

The RSL-Series also feature a range of “Slimline” hex cassettes that provide superior access to narrow spaces, like a blow-out-preventer, without compromising on tool durability or torque output.

The RSL-Series Hydraulic Torque Wrenches are field proven tools. RSL Torque Wrenches have been the most recognizable tools in Hydratight’s bolting portfolio for more than a decade. In January, 2019 we began merging two leading bolting companies; Enerpac and Hydratight into a single company. The RSL Wrenches are the first of many Hydratight tools which will be added to Enerpac’s product line.

Hex size range: 7/8 in. to 6-1/8 in. (22mm -155mm)

Maximum output torque: 1408 ft-lbs. to 28002 ft-lbs. at 10,000 PSI



  • Safety and Performance
    • Innovative design that completely encloses all moving parts and minimizes pinch points
    • 30-35° rotation angle provides added productivity while avoiding “tool lock on” which is common with some torque wrench designs
  • Simplicity
    • Simple robust alloy steel design with just three moving parts for reduced maintenance
    • Robust handles are available for both sides and the tops of cassettes to allow for extra maneuverability
    • Designed to give optimum strength to weight and torque to weight ratios
    • Minimum nose radius for trouble-free tool fit.
  • Versatility
    • Interchangeable cassette design
    • Wide range of hexagon sizes available for all applications
    • Reaction arm has a simple dial lock for rapid change
