GENERAL INSTRUCTIONS
1.1
Scope: This safety guide provides instructions for selecting and using
(including assembling, installing, and maintaining) these Products. For
convenience, all rubber and/or thermoplastic products commonly called “hose”
or “tubing” are called “Hose” in this safety guide. All assemblies made with
Hose are called “Hose Assemblies”. All products commonly called “fittings” or
“couplings” are called “Fittings”. All related accessories (including crimping and
swaging machines and tooling) are called “Related Accessories”. This safety
guide is a supplement to and is to be used with, the specific Parker publications
for the specific Hose, Fittings and Related Accessories that are being considered
for use.
1.2
Fail-Safe: Hose, and 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 or Hose Assembly or Fitting will not
endanger persons or property.
1.3
Distribution: Provide a copy of this safety guide to each person that
is responsible for selecting or using Hose and Fitting products. Do not select or
use Parker Hose or Fittings without thoroughly reading and understanding this
safety guide as well as the specific Parker publications for the products considered
or selected.
1.4
User Responsibility: Due to the wide variety of operating conditions
and applications for Hose and Fittings, Parker and its distributors do not represent
or warrant that any particular Hose or Fitting is suitable for any specific 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 final selection of the Hose 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 and Fittings are used.
• Assuring compliance with all applicable government and
industry standards.
1.5
Additional Questions: Call the appropriate Parker technical service
department if you have any questions or require any additional information. See
the Parker publication for the product being considered or used, or call 1-800-
CPARKER, or go to www.parker.com, for telephone numbers of the appropriate
technical service department.

HOSE AND FITTING SELECTION INSTRUCTIONS
2.1
Electrical Conductivity: Certain applications require that the Hose
be nonconductive to prevent electrical current flow. Other applications require
the Hose and the Fitting and the Hose/Fitting interface to be sufficiently conductive
to drain off static electricity. Extreme care must be exercised when selecting
Hose and Fittings for these or any other applications in which electrical
conductivity or nonconductivity is a factor.
The electrical conductivity or nonconductivity of Hose 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 to make the Hose and the Fittings,
Fitting finish (some Fitting finishes are electrically conductive while others are
nonconductive), manufacturing methods (including moisture control), how the
Fittings contact the Hose, age and amount of deterioration or damage or other
changes, moisture content of the Hose at any particular time, and other factors.
The following are considerations for electrically nonconductive and conductive
Hose. For other applications consult the individual catalog pages and the
appropriate industry or regulatory standards for proper selection.
2.1.1
Electrically Nonconductive Hose: Certain applications require that
the Hose be nonconductive to prevent electrical current flow or to maintain
electrical isolation. For these applications that require Hose to be electrically
nonconductive, including but not limited to applications near high voltage electric
lines, only special nonconductive Hose can be used. The manufacturer of the
equipment in which the nonconductive Hose is to be used must be consulted to
be certain that the Hose and Fittings that are selected are proper for the
application. Do not use any Parker Hose or Fitting for any such application
requiring nonconductive Hose, including but not limited to applications near high
voltage electric lines, unless (i) the application is expressly approved in the Parker
technical publication for the product, (ii) the Hose is marked “nonconductive”,
and (iii) the manufacturer of the equipment on which the Hose is to be used
specifically approves the particular Parker Hose and Fitting for such use.
2.1.2
Electrically Conductive Hose: Parker manufacturers special Hose
for certain applications that require electrically conductive Hose.
Parker manufactures special Hose for conveying paint in airless paint spraying
applications. This Hose is labeled “Electrically Conductive Airless Paint Spray
Hose” on its layline and packaging. This Hose must be properly connected to
the appropriate Parker Fittings and properly grounded in order to dissipate
dangerous static charge buildup, which occurs in all airless paint spraying
applications. Do not use any other Hose for airless paint spraying, even if
electrically conductive. Use of any other Hose or failure to properly connect the
Hose can cause a fire or an explosion resulting in death, personal injury, and
property damage.
Parker manufactures a special Hose for certain compressed natural gas (“CNG”)
applications where static electricity buildup may occur. Parker CNG Hose
assemblies comply with AGA Requirements 1-93, “Hoses for Natural Gas
Vehicles and Fuel Dispensers”. This Hose is labeled “Electrically Conductive
for CNG Use” on its layline and packaging. This Hose must be properly connected
to the appropriate Parker Fittings and properly grounded in order to dissipate
dangerous static charge buildup, which occurs in, for example, high velocity
CNG dispensing or transfer. Do not use any other Hose for CNG applications
where static charge buildup may occur, even if electrically conductive. Use of
other Hoses in CNG applications or failure to properly connect or ground this
Hose can cause a fire or an explosion resulting in death, personal injury, and
property damage. Care must also be taken to protect against CNG permeation
through the Hose wall. See section 2.6, Permeation, for more information. Parker
CNG Hose is intended for dispenser and vehicle use at a maximum temperature
of 180°F. Parker CNG Hose should not be used in confined spaces or unventilated
areas or areas exceeding 180°F. Final assemblies must be tested for leaks.
CNG Hose Assemblies should be tested on a monthly basis for conductivity per
AGA 1-93.
Parker Safety Guide for Selecting and Using Hose, Tubing, Fittings and Related Accessories
Parker Publication No. 4400-B.1
Revised: May, 2002
WARNING: Failure or improper selection or improper use of hose, tubing, fittings, assemblies or related accessories (“Products”) can cause death, personal injury and property
damage. Possible consequences of failure or improper selection or improper use of these Products include but are not limited to:
• Fittings thrown off at high speed.
• High velocity fluid discharge.
• Explosion or burning of the conveyed fluid.
• Electrocution from high voltage electric powerlines.
• Contact with suddenly moving or falling objects that are controlled by the conveyed fluid.
• Injections by high-pressure fluid discharge.
• Dangerously whipping Hose.
• Contact with conveyed fluids that may be hot, cold, toxic or otherwise injurious.
• Sparking or explosion caused by static electricity buildup or other sources of electricity.
• Sparking or explosion while spraying paint or flammable liquids.
• Injuries resulting from inhalation, ingestion or exposure to fluids.
Before selecting or using any of these Products, it is important that you read and follow the instructions below. Only Hose from Parker’s Stratoflex Products Division is approved
for in flight aerospace applications, and no other Hose can be used for such in flight applications.
