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.
