Wrong Right
Hose too short - hose is
bent at the connections
Provide sufficiently long
neutral hose ends (3-5 x
DN)
Wrong Right
Excessive bending load
at the connections
Pipe elbows fitted
Wrong Right
Incorrect installation -
compression along the
longitudinal axis
Pipe elbows fitted
Wrong Right
Torsion - hose axis and
direction of movement
not in the same plane
The pipe axes must be
parallel and in the same
plane as the direction of
movement
Important - twisting of the
hoses can also be
caused during installa-
tion.
When attach-
ing/detaching a hose, al-
ways hold it in place with
a second wrench
