Warning
These products are intended for use in industrial compressed air systems only. Do not use these products where
pressures
and
temperatures
can
exceed those listed under ‘Technical Data’.
Before using these products with fluids other than those specified, for non-industrial applications, life-support systems, or other applications not
within published specifications, consult Norgren.
Through misuse, age, or malfunction, components used in fluid power systems can fail in various modes. The system designer is warned to
consider the failure modes of all component parts used in fluid power systems and to provide adequate safeguards to prevent personal injury or
damage to equipment in the event of such failure.
System designers must provide a warning to end users in the system instructional manual if protection against a failure mode cannot be
adequately provided.
System designers and end users are cautioned to review specific warnings found in instruction sheets packed and shipped with these products
where applicable.
