HYDRAULIC HOSE

Introducing HYDRAULIC HOSE products.

01.COMPONENTS SELECTION

Select the specified hoses, ferrules and inserts
using the most updated Catalogue release

02.HOSE CUTTING

Cut squarely the hose (cut angle must be ≤ 3).
In order to ensure a correct cut (minimum
rosetting and tulip effect due to the heat

damage to the rubber), it is recommended
to use the appropriate blade type

·	wire spiral, large bore wire braided (> DN31) & Spirtex: use a smooth blade.
·	wire braided small bore (≤ DN31) : use a serrated blade Use of scalloped blade (with wavy edge) is acceptable for all hose types

03.SKIVING OPERATIONS

When skiving is required, set-up the skiving
machine such that the front edge of the knife
is set to the correct length (refer to
crimping
chart: tolerance +/-0.5 mm; +/0.02 inch).
It is important to remove the maximum
thickness of the rubber hose cover
without
damaging or displacing the reinforcement
steel wires.

04.FITTINGS MOUNTING

·	In case of two-piece fittings, mount the ferrule fully onto the hose, and then push the insert fully into the hose.
·	In case of one-piece fittings, mark the hose insertion depth (distance from the bottom of the ferrule to its end to be measured by calipers) on the hose cover and push the coupling fully into the hose up to the mark made on the hose cover. Especially in case of large hose sizes and lock type fittings the use of a proper pushing machine is recommended to facilitate this operation

05.DIE-SETS SELECTION FOR MANULI CRIMPING MACHINES

Choose the die-set closest to and smaller
than the specified Crimping Diameter
– 0.4 mm.
The 0.4 mm correction is
necessary to assure the requested
crimping diameter, allowing some ferrule
bulging among the dies, when
crimping
close to the dies closure diameter.
