1. Provide for length change.
In straight hose installations, allow
enough length in the hose line to provide
for changes in length that will occur when
pressure is applied.

2. Avoid twisting and orient properly.
Do not twist hose during installation. This
can be determined by the printed lay-
line on the hose. Pressure applied to a
twisted hose can cause hose failure.

3. Protect from hazardous environment.
Keep hose away from hot parts. High
ambient temperature will shorten hose
life. It should be routed away from the
heat source, and insulated.

4. Avoid mechanical stress.
Use elbows and adapters in the
installation to relieve stress on the
assembly.

5. Use proper bend radius.
Keep the bend radius of the hose as
large as possible to avoid collapsing of
the hose and restriction of flow.
Minimum bend radius is measured on
the inside bend of the hose as illustrated
in the opposite figure.
