C.
Installation with Bending — When bends are
required, the radii shown in Figure 23 should
be maintained for normal installation with
no flexing. A larger radius than the minimum
allowed is preferred.
D.
Flexing Installations — The following precautions
will help prevent kinking:
(1)
Hose should be bent in same plane
as movement to avoid twisting. See
Figure 24.
(2)
Hose flexing in two directions should
be clamped at the point where the
hose changes planes. (This has effect
of dividing hose into sections, each in
one plane.) See Figure 24.

Torque Values, Installation
Swivel Connections — Install flared and Aeroquip
Globeseal flareless swivel connections using position-
tightening procedure as follows:
Step 1. Locate assembly in desired position and then
turn nut finger tight.
Step 2. While restraining nipple hex with one wrench,
tighten nut to the appropriate torque value in
Table VII.
Do not overtighten.
Step 3. If connection leaks during pressure check,
loosen and completely disconnect the nut.
Inspect the fitting for damaged sealing
surfaces, present of foreign material or
damage from previous overtightening.

Fittings Used On Aeroquip AE246 Hose
In addition to the above general procedures, the
following caution should be observed.
Caution:
Do not place wrench on socket of hose fitting
when installing hose lines.
