HOSES & HOSE COUPLINGS
GS-HYDRO PRODUCT CATALOGUE
Assembly and installation
When hose installation is straight, allow enough slack in hose
line to provide for length changes which will occur when pres-
sure is applied.
Prevent twisting and distortion by bending hose in same plane as
the motion of the boss to which hose is connected.
User proper angle adaptors to avoid sharp twist or bend in hose. Adequate hose length is necessary to distribute movement on
flexing applications and to avoid abrasion.
When radius is below the required minimum, use an angle adap-
tor to avoid sharp bends.
Avoid twisting of hose lines bent in two planes by clamping hose
at change of plane.

Correct hose installation is essential for safe and
satisfactory performance. The size of the hoses
impacts the installation recommendations. This
manual has therefore been split in recommendation for hoses up to 2” and recommendation
larger than 2”.
1. Hoses up to 2” When installing hoses, avoid twisting the hose as
the hose will try to straighten under pressure.
MIN. 10°
Always provide some angle on straight
hose installations, this reduces forces
and ensures that hose is only bending i
one direction. The Hose must have some
slack to compensate for hose length
variations.
Hose routing tips:
Danfoss recommends installing hose whip
restraints whenever your pressurized hose
assemblies are in proximity to personnel or
crucial equipment.
Check with these examples when installing
your hoses.
This can cause hose failure via hose blowout
from the tting and/or hose burst at the point of
strain.

When radius is below the required minimum, use an angle adap-
tor to avoid sharp bends.
At radius below required minimum, angle
adapters should be used to prevent sharp
hose bends.
NO
PRESSURE
To allow the hose to expand when
pressurized, clamps should not be used at
bends. If possible, do not clamp high and
low pressure lines together.

WRONG RIGHT
To prevent hose collapse and ow restriction,
hose bend radii should be kept as large as
possible. Tight bends can also compromise
the hose reinforcement and cause premature
hose failure. Refer to hose specication table
on page 6 for minimum bend radii.
