HOSE ASSEMBLY

ASSEMBLY HOSE PREPARING 2

When cutting the hose, use a sharp disk: a blunt disk can cause an irregular cut and damage of the extremities of the hose. Remember that the cut must be perpendicular to the axis of the hose. An incorrect cut can provoke:

FERRULE BREAKING due to non uniform compression;
ASSEMBLY LEAKAGE due to holding loss in the coupling area.

After the cut proceed with cleaning the hose from the residuals of rubber and dirt.

SKIVE

To skive correctly as per the given tables use a tolerance of +/-0,3mm. Remove as much rubber as possible without damaging the steel reinforcement.


raccordatore

A skive that is too short could have consequence of fitting not being fully inserted thus causing a “Blow off “of the fitting.

A skive too long exposes the reinforcement to environmental agents, causing corrosion and possible burst close to the ferrule.

Remember

In case of spiral hose reinforcement the skive tool must rotate following spiral direction (therefore in the opposite sense for internal and external skiving).
