Parker Safety Guide
1.0 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 “Re-
lated 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 with-
out 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 se-
lect or use Parker Hose or Fittings without thoroughly reading and under-
standing 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 repre-
sent or warrant that any particular Hose or Fitting is suitable for any spe-
cific 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 stan-
dards.
1.5 Additional Questions: Call the appropriate Parker technical service de-
partment 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.
2.0 HOSE AND FITTING SELECTION INSTRUCTIONS
2.1 Electrical Conductivity: Certain applications require that the Hose be
nonconductive to prevent electrical current flow. Other applications re-
quire the Hose and the Fitting and the Hose/Fitting interface to be suffi-
ciently conductive to drain off static electricity. Extreme care must be
exercised when selecting Hose and Fittings for these or any other appli-
cations in which electrical conductivity or nonconductivity is a factor.
The electrical conductivity or nonconductivity of Hose and Fittings is de-
pendent 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 electri-
cally conductive while others are nonconductive), manufacturing meth-
ods (including moisture control), how the Fittings contact the Hose, age
and amount of deterioration or damage or other changes, moisture con-
tent of the Hose at any particular time, and other factors.
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.
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.
• 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.
The following are considerations for electrically nonconductive and con-
ductive 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 electri-
cally 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 manu-
facturer 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 manufactures special Hose for
certain applications that require electrically conductive Hose.
Parker manufactures special Hose for conveying paint in airless paint spray-
ing applications. This Hose is labeled “Electrically ConductiveAirless 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 re-
sulting 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 “Electri-
cally Conductive for CNG Use” on its layline and packaging. This Hose
must be properly connected to the appropriate Parker Fittings and prop-
erly 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 dam-
age. 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 tem-
perature of 180°F. Parker CNG Hose should not be used in confined
spaces or unventilated areas or areas exceeding 180°F. Final assem-
blies must be tested for leaks. CNG Hose Assemblies should be tested
on a monthly basis for conductivity per AGA 1-93.
Parker manufactures special Hose for aerospace in-flight applications.
Aerospace in-flight applications employing Hose to transmit fuel, lubricat-
ing fluids and hydraulic fluids require a special Hose with a conductive
inner tube. This Hose for in-flight applications is available only fromParker’s
Stratoflex Products Division. Do not use any other Parker Hose for in-
flight applications, even if electrically conductive. Use of other Hoses for
in-flight applications or failure to properly connect or ground this Hose can
