HYDRAULIC HOSE INSTALLATION GUIDE
1. Use elbows and adapters in the installation to
relieve strain on the assembly, and to provide
easier and neater installations that are accessible
for inspection and maintenance. Remember
that metal end
fi
ttings cannot be considered as
part of the
fl
exible portion of the assembly.
2. Install hose runs to avoid rubbing or abrasion.
Clamps are often needed to support long runs
of hose or to keep hose away from moving
parts. It is important that the clamps be of
the correct size. A clamp that is too large will
allow the hose to move in the clamp causing
abrasion at this point.
3. In straight hose installations allow enough slack
in the hose line to provide for changes in length
that will occur when pressure is applied. This
change in length can be from +2% to -4%.
4. Do not twist hose during installation. This
can be determined by the printed layline on
the hose. Pressure applied to a twisted hose
can cause hose failure or loosening of the
connections.
5. Keep hose away from hot parts. High ambient
temperature will shorten hose life. If you cannot
route it away from the heat source, insulate it.
6. Keep the bend radii of the hose as large
as possible to avoid hose collapsing and
restriction of
fl
ow. Follow catalog specs on
minimum bend radii.
