General Information and Specifications
2.3.3 Hydraulic Hose Torque Chart
Note: By definition the “Flats Method“ will contain some
variance.
Flats Method:
1. If equipped, lubricate o-ring with hydraulic oil. Hand
tighten the swivel nut until no lateral movement of the
swivel nut can be detected. Average hand torque is 4
Nm (3 lb-ft).
2. Mark a dot on one of the swivel nut flats and another
dot in line on the hex of the adapter it’s connecting to.
3. Use the double wrench method while tightening to
avoid hose twist.
4. Tighten the connection 6.35 mm (0.25 in) or 1.5 flats.
5. After the connection has been properly tightened, mark
a straight line across the connecting parts, not covering
the dots indicating that the connection has been
properly tightened.
