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 Specifications.

Before using these products with fluids other than those specified, for
nonindustrial 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 modes. 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. System designers
should also provide for all OSHA requirements including Title 29 CFR 1910.147
Lockout/Tagout.

It should be recognized that warnings are valid for any product, regardless of
manufacturer, and are not restricted to products manufactured by NORGREN.
NORGREN’s reputation for product quality and performance is well established.
