RSL Torque Wrench
3 Wrench Description and Terminology
3.1 Description
3.1.1 RSL square drive and hex tools are offered
in seven standard models:
3.1.2 See Section 3.2 for definitions of key terms.
3.1.3 RSL torque wrenches (tools):
a. Enable user to accomplish bolting
tasks with high torque, accuracy, and
efficiency.
b. Are powered by a hydraulic pump
operated at pressures:
i. Up to 10000 psi [690 bar] for advance
stroke.
ii. From 1500 to 1700 psi [103 to 117 bar]
for retract stroke.
c. Are used to remove fastener tension
(loosen/breakout).
d. Apply a specific tension to studs, bolts
and cap screws (tightening/makeup).
Desired fastener tension is achieved by:
i. Proper flange alignment, assembly, etc.
ii. Controlling fastener frictional forces
between stud/nut, and nut/flange by:
1. Using lubricant with known friction
coefficient on threads, nut face, etc.
2. Using bolts/nuts which are not
damaged or dirty.
iii. Applying proper torque value for a
specific bolt material, bolt size, and
lubricant.
1. Refer to torque vs. pressure
certificate of precision for each tool,
or Section 7.9 for the nominal torque
vs. pressure table.
2. Precisely control pump pressure.
• Do not modify any equipment or accessories.
• Contact Enerpac for special applications or
modifications.
• Unauthorized modifications may cause injury
and/or damage plus invalidate warranty.

3.2.6 Torque – The tendency of a force to rotate
an object about an axis (twist). Force times
distance from object axis.
3.2.7 Torque vs. Pressure Certificate of Precision
– A torque vs. pressure table and curve for
a given torque wrench drive and wrench
assembly.
3.2.8 QC’s – Quick Connect Couplings for hoses.
3.2.9 QD’s – Quick Disconnect Couplings for
