Section 5 – Procedures
Using a Torque Wrench
1.
This method is applicable for JIC (37°) and
FFOR (Flat Face O-ring) hose ends and fittings,
wherever the components are accessible with
torque wrench / crow’s foot tools.
2.
Align the hose end or fitting to the mating
component.
3.
Install the nut two or three turns by hand to
assure proper alignment. Jiggle the hose while
tightening to ensure the faces contact fully.
4.
Using a properly calibrated torque wrench,
tighten the coupling using a smooth, even
motion until an indication (audible click) is
heard and felt. Do NOT over tighten. For
recommended torque values, refer to
2 .4 Torque
Specifications for Hydraulic Couplings & Hoses
.
Apply a drop of torque seal to the connection.
5.2-8 Torquing Using the Flats-From-
Wrench-Resistance Method
This method is applicable for JIC (37°) and FFOR
(Flat Face O-ring) hose ends only, wherever the
components are inaccessible with torque wrench/
crow’s foot tools, or when a properly calibrated torque
wrench is not available.
1.
Align the hose end or fitting to the mating
component.
2.
Install the swivel hose end nut hand tight to
the fitting to assure proper alignment. Jiggle
the hose while tightening to ensure the faces
contact fully.
3.
Tighten the nut using a box wrench until minor
resistance is felt.
4.
Mark the position of the nut relative to the fitting
with a marking device (paint marker).
Mark the hose
end and fitting
5.
Referencing the following table, use a second
box wrench to tighten the nut the appropriate
number of flats past the mark. Do NOT over
tighten.
