Crystal Safety Guide for Using Hose Assemblies and Fittings 1
INSTRUCTIONS
Scope
—
This safety guide provides instructions for selecting and using (including installing and maintaining) these products. For convenience, all assemblies made
with Hose are called “Hose Assemblies”. All products commonly called “ttings”, “adapters”, or “couplings” are called “Fittings”. This safety guide is a supplement
to and is to be used with, the specic Crystal Engineering publications for the specic Hose Assemblies and Fittings that are being considered for use.
Fail Safe
Hose Assemblies and Fittings can and do fail without warning for many reasons. Design all systems and equipment in a fail-safe mode, so that failure of the
Hose Assembly or Fitting will not endanger persons or property.
Distribution
Provide a copy of this safety guide to each person that is responsible for selecting or using Hose Assembly and Fitting products. Do not select or use Crystal
Engineering Hose Assemblies or Fittings without thoroughly reading and understanding this safety guide as well as the specic Crystal Engineering publica-
tions for the products considered or selected.

User Responsibility
Due to the wide variety of operating conditions and applications for Hose Assemblies and Fittings, Crystal Engineering and its distributors do not represent
or warrant that any particular Hose Assembly or Fitting is suitable for any specic end use system. This safety guide does not analyze all technical parameters
that must be considered in selecting a product. The user, through its own analysis and testing, is solely responsible for:
Making the nal selection of the Hose Assembly and Fitting.
•
Assuring that the user’s requirements are met and that the application presents no health or safety hazards.
•
Providing all appropriate health and safety warnings on the equipment on which the Hose Assemblies and Fittings are used.
•
Assuring compliance with all applicable government and industry standards.
•

HOSE ASSEMBLY AND FITTING SELECTION INSTRUCTIONS
Crystal Engineering does not manufacture Hose Assemblies and Fittings that are specically designed to be electrically conductive or electrically
nonconductive.
—
Electrical Conductivity
Certain applications require that the Hose Assemblies be nonconductive to prevent electrical current ow. Other applications require the Hose Assemblies/
Fitting interface to be suciently conductive to drain o static electricity. Extreme care must be exercised when selecting Hose Assemblies and Fittings for
these or any other applications in which electrical conductivity or nonconductivity is a factor. The electrical conductivity or nonconductivity of Hose Assem
blies and Fittings is dependent upon many factors and may be susceptible to change. These factors include but are not limited to the various materials used
o make the Hose Assemblies and the Fittings, Fitting nish (some Fitting nishes are electrically conductive while others are nonconductive), manufacturing
t
methods (including moisture control), how the Fittings contact the Hose Assemblies, age and amount of deterioration or damage or other changes, moisture
content of the Hose Assemblies at any particular time, and other factors.
Electrically Conductive Hose Assemblies: Crystal Engineering does not manufacture special Hose Assemblies for certain applications that require electri
cally conductive Hose Assemblies. These Hose Assemblies may be labeled “Electrically Conductive Airless Paint Spray Hose Assemblies” on its layline and
aging. These Hose Assemblies must be properly connected to appropriate Fittings and properly grounded in order to dissipate dangerous static charge
pack
buildup, which occurs in all airless paint spraying applications.
Airless Paint Systems Use: Do not use any Crystal Engineering Hose Assemblies for airless paint spraying. Use of any other Hose Assemblies or failure to
properly connect the Hose Assemblies can cause a re or an explosion resulting in death, personal injury, and property damage.
