Replacing hose lines
As a general rule, even when stored properly and subjected to permissible stress during use, all
hose lines are subject to natural aging, which changes the material and composite properties
and reduces the performance of the hose lines.
This limits the service life of a hose line and the operator must ensure that hose lines are replaced at
appropriate intervals.
Immediate replacement of hose lines
Hose lines must be replaced immediately in the event of the following defects:

External visible damage to the hose line or fittings.

 Internal damage to the tube or the reinforcement. 

Leakage from the hose line or the fittings.

 Deformation of the hose line or the fittings. 
