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 fittings cannot be considered as
part of the flexible 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 flow. Follow catalog specs on
minimum bend radii�
