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�
