EGA Master’s hydraulic torque wrenches have been designed for controlled tightening of nut-bolt connections.

The remotely controlled hydraulic flow and pressure supplied by EGA Master hydraulic power units provide the rotation of the nut on the bolt.

The assortment of square drive and hexagonal cassettes hydraulic torque wrenches allows tightening of a very wide range of nut sizes, both in millimeters and inches. Their small dimensions and high durability make them the perfect tool for several sectors: petrochemical industry, wind sector, power generation, naval sector, etc. Square drive wrenches need additional impact socket wrenches while hexagonal cassette ones don't.


The 360˚x360˚ swivel allows
a total mobility of the hose,
making its use easy and confortable


Laser engraved torque chart for faster access

2.360˚ swivel reaction arm for a correct fitting on any aplication
3.Allows the use of the tool without reaction arm
4.Allows quick change of direction pushing the square drive, without additional tools

Mono-body housing

2. Balanced drive rod
Wide load-free piston movement

3. Multi-tooth drive segment
Ensures up to 27 degree torque stroke

4. Anti-back lash mechanism
Provides hands free operation

5. Laser engraved torque chart
No more searching for charts

6. Multi-tooth ratchet
Strong Vascomax teeth provide strength, accuracy and 27 degree torque stroke

7. One piece drive plate
One piece Vascomax drive plate provides longer life and increased durability

8. Push-through drive
Simply push to switch from loosen to tighten

9. Single seal piston
Assures extended maintenance free operation

10. Direct housing reaction

13. Reaction arm release button
Protected within reaction arm housing

14. 360°x360° swivel
Allows hose to be cleared on all applications

15. No drip quick connect couplers
Assures easy and safe operation

16. Steel alloy piston
Robust composition allows for longer operation cycle


1. Compact size for use in inaccesible places
2. Without tools. The pin can be easily removed to change the cassette
3. Small nose radius to use in small spaces


“Peanut-shaped” cylinder

Fit both the cylinder and link in confined areas

2. Engagement rod
Automatically engages link on the first stroke 

3. Never-lock drive paw
Ensures tool will never lock on

4. Multi-tooth ratchet  
Allows for 27 degree torque stroke accuracy   

5. One piece drive plate
Robust alloy provides for small nose radius

6. Link pin
One pin for link to cylinder engagement, no tools required

7. In-line reaction pad
Assures free reaction every time

8. Steel alignment pin
Assures equal load displacement between side plates

9. Completely flat design
Cylinder and link width are equal for tight fits

10. 360˚x360˚ swivel
Allows hose to be cleared on all applications

11. Propietary piston seal
Provides years of maintenance free use

12. Slider
Prevents wear of piston and drive plate and reduces cost of repairs

*Some situations where hexagonal torque wrenches can be useful


EGA Master’s hydraulic power unit pumps have been designed according to the needs of the end user. They enable simultaneous use of four wrenches. EGA Master power units are manufactured to work in adverse environments, allowing pressure adjustment to assure the correct torque output to each application.

In addition to the electric drive hydraulic pumps (115VAC or 230VAC), EGA Master provides air drive hydraulic pumps to use them in explosive environments or in applications where the electricity is not available.
