Safety Instructions For Assembly - Parker EO2 – FORM F3 Manual De Instrucciones

•
Tubelines need to be adapted tension free of the relevant connectors before assembly.
An easy turning of the nut is required for the complete thread length. Otherwise leakage can
occur. In extreme cases with additional vibrations tube cracks can occur.
•
Vibrations have to be intercepted by tube clamps. Independent vibration units need to be
separated with hoses. Otherwise tube cracks can occur.

Safety Instructions for Assembly

During a progressive ring and EO-2 fitting assembly the tube has to bottom up in the stud or in the tool.
Without tube bottoming the ring cannot bite sufficiently. Under load the connection can fail due to tube
shear.
Incompletely assembly will reduce the pressure and vibration capability of a fitting. It can reduce the
life cycle time of a connection and leakage can occur. In extreme cases the connection can fail due to
tube shear or tube crack. Presented progressive ring fittings need a final assembly according to
assembly instructions.
After opening a tube connection, the unit has to be retighten with the same force used during prior
assembly. Under tightening can result in leakage and can reduce the vibration capability.
Over tightening can reduce the possibilities of repeated assembly. In extreme cases the components
can be destroyed.
Stainless steel progressive ring fittings have to be presented in hardened tools. Otherwise the
connection may fail under load due to tube shear.
