Pressure
When considering hose pressure,
it’s important to know both the
system working pressure and any
surge pressures and spikes.
Hose selection must be made
so that the published maximum
working pressure of the hose is
equal to or greater than the
maximum system pressure.
Surge pressures or peak transient
pressures in the system must be
below the published maximum
working pressure for the hose.
Each Parker hose has a pressure
rating which can be found on the
Hose Overview Chart on page A-6,
to A-7 and in Section E.
All Parker hydraulic hoses have
passed the industry rated specifica- components. In this case the
tions for burst pressure and carry a
4:1 design factor unless otherwise
noted. Burst pressure ratings for
hose are for manufacturing test
purposes only. They are not an
indication that the product can
be used above the published
maximum working pressure.
It is for this reason that the burst
pressure ratings have been
removed from the hose charts
within the catalog.
Care must also be taken when
looking at the “weakest link” of the
hose assembly. A hose assembly
is rated at the maximum working
pressure of the hose and the fitting
component. Therefore the maxi-
mum working pressure of the hose
assembly is the lesser of the rated
