Parker Safety Guide for Selecting and Using Hose, Tubing, Fittings and Related Accessories
Publication No. 4400-B.1
Revised: November 2007
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 im-
properselectionor improperuseof theseProducts includebutarenot 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.

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 as-
semblies made with Hose are called “Hose Assemblies”. All products
commonly called “fittings”, “couplings” or “adapters” are called “Fittings”.
All related accessories (including crimping and swaging machines and
tooling) are called “Related Accessories”. This safety guide is a supple-
ment 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. Parker publications are available at
. SAE J1273
(
) and ISO 17165 2
) also pro-
vide recommended practices for hydraulic Hose Assemblies.
1.2
Fail-Safe: Hose, 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, Hose
Assembly or Fitting will not endanger persons or property.
1.3
Distribution: Provide a copy of this safety guide to each person re-
sponsible 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.
1.4
User Responsibility: Due to the wide variety of operating conditions
and applications for Hose and Fittings, Parker does 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 Products.
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 Products are used.
Assuringcompliancewithallapplicablegovernmentand industrystandards.
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 Products being considered or used, or
call 1 800 CPARKER, or go to
, 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 Fittings 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 depen-
dent 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 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 manufac-
turer 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 Fittings 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 Fittings 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 Conductive Airless Paint
Spray Hose” on its layline and packaging. This Hose must be properly con-
nected 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 the requirements of ANSI/IAS NGV 4.2-1999;
CSA 12.52-M99, “Hoses for Natural Gas Vehicles and Dispensing Systems”
(
. 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
