Hydraulic Hose
Hose assemblies in operation should be inspected frequently for leakage, kinking, abrasion, corrosion or
other signs of wear or damage� Worn or damaged hose assemblies should be replaced immediately�
Testing should be conducted in approved test stands with adequate guards to protect the
operator� Failure to comply with this requirement could result in death or serious injury�
Clean
Clean assembly by blowing out with clean compressed air� Assemblies
may be rinsed out with mineral spirits if the tube stock is compatible with
oil, otherwise hot water at 150°F (65�55° C) maximum may be used�
Inspect
Examine hose assembly internally for cut or bulged tube, obstructions,
and cleanliness. For segment style fittings, be sure that the hose butts up
against the nipple shoulder; band and retaining ring are properly set and
tight, and segments are properly spaced� Check for proper gap between
nut and socket or hex and socket� Nuts should swivel freely� Check the
layline of the hose to be sure the assembly is not twisted� Cap the ends of
the hose with plastic covers to keep clean�
Test
The hose assembly should be hydrostatically tested at twice the
recommended working pressure of the hose�
Test pressure should be held for not more than one minute and not less
than 30 seconds� When test pressure is reached, visually inspect hose
assembly for: 1� Any leaks or signs of weakness� 2� Any movement of the
hose fitting in relation to the hose. Any of these defects are cause for
rejection�
Storage and Handling
Hose should be stored in a dark, dry atmosphere away from electrical equipment, and the temperature
should not exceed 90° F (32° C)�
