Application
Before selecting a hose, it is
important to consider how the hose
assembly will be used. Answering
the following questions may help:
• What type of equipment
is involved?
• What are the environmental
factors?
• Are mechanical loads
applied to the assembly?
• Will the routing be confned?
• What about hose fttings –
permanent or feld
attachable?
• Will the assembly be
subjected to abrasion?
Sometimes specifc applications
require specifc hoses. For
example, applications where
hoses will encounter rubbing or
abrasive surfaces, would be best
handled by our family of abrasion-
resistant hose with both Tough
and Super Tough covers.
When application space is tight,
bend radius is another important
consideration. Parker offers a full
line of hoses designed for one-half
SAE bend radius at full SAE-rated
pressures. We ofer hoses with
increased fexibility and smaller
outer diameters enabling faster,
easier routing in small spaces,
reducing both hose length
and inventory requirements.
Industry standards set specifc
requirements concerning
construction type, size, tolerances,
burst pressure, and impulse cycles
of hoses. Parker hydraulic hoses
meet or exceed standards such as:
• SAE (Society of Automotive
Engineers)
• EN (European Norm)
• DIN (Deutsches Institut für
Normung)
• ISO (International Organization
for Standardization)
Hose Hint
When considering the bend
radius of a hose assembly, a
minimum straight length of twice
the hose’s outside diameter
should be allowed between
the hose fitting and the point
at which the bend starts.
