Parker Safety Guide
for Selecting and Using Hose, Tubing, Fittings and Related Accessories
Parker Publication No. 4400-B.1
Revised: November, 2007
WARNING: Failure or improper selection or improper use of hose, tubing, fttings, 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 fuid discharge.
• Explosion or burning of the conveyed fuid.
• Electrocution from high voltage electric powerlines.
• Contact with suddenly moving or falling objects that are controlled by
the conveyed fuid.
• Injections by high-pressure fuid discharge.
• Dangerously whipping Hose.
• Contact with conveyed fuids 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 fammable liquids.
• Injuries resulting from inhalation, ingestion or exposure to fuids.
2.1.1 Electrically Nonconductive Hose:
Certain applications require that the Hose
be nonconductive to prevent electrical current fow 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 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 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
specifcally 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 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 fre 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”
(www.ansi.org). 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 dan-
gerous 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 fre 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 (82°C). Parker CNG Hose should not be used in confned spaces or
unventilated areas or areas exceeding 180°F (82°C). Final assemblies must
be tested for leaks. CNG Hose Assemblies should be tested on a monthly
basis for conductivity per ANSI/IAS NGV 4.2-1999; CSA 12.52-M99.
Parker manufactures special Hose for aerospace in-fight applications.
Aerospace in-fight applications employing Hose to transmit fuel, lubricating
fuids and hydraulic fuids require a special Hose with a conductive inner tube.
This Hose for in-fight applications is available only from Parker’s Stratofex
Products Division. Do not use any other Parker Hose for in-fight applications,
even if electrically conductive. Use of other Hoses for in-fight applications
or failure to properly connect or ground this Hose can cause a fre or an
explosion resulting in death, personal injury and property damage. These
Hose assemblies for in-fight applications must meet all applicable aerospace
industry, aircraft engine and aircraft requirements.
2.2 Pressure:
Hose selection must be made so that the published maximum
working pressure of the Hose and Fittings are equal to or greater than
the maximum system pressure. The maximum working pressure of a Hose
Assembly is the lower of the respective published maximumworking pressures
of the Hose and the Fittings used.Surge pressures or peak transient pressures
Before selecting or using any of these Products, it is important that you read and follow the instructions below. Only Hose from Parker’s Stratofex Products
Division is approved for in-fight aerospace applications.

ENERAL INSTRUCTIONS
1.1 Scope:
This safety guide provides instructions for selecting and using (includ-
ing 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 “fttings”, “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 supplement to and is to be used with the specifc Parker
publications for the specifc Hose, Fittings and Related Accessories that are
being considered for use. Parker publications are available at www.parker.
com.SAE J1273 (www.sae.org) and ISO 17165-2 (www.ansi.org) also provide
recommended practices for hydraulic Hose Assemblies.
1.2 Fail-Safe:
Hose, HoseAssemblies and Fittings can and do fail without warning for
many reasons.Designall systems andequipment ina fail-safemode, 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 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 specifc 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 specifc end use system.

2.0 HOSE AND FITTINGS SELECTION INSTRUCTIONS
2.1 Electrical Conductivity:
Certain applications require that the Hose be noncon-
ductive to prevent electrical current fow. Other applications require the Hose
and the Fittings and the Hose/Fitting interface to be suffciently conductive
to drain off static electricity. Extreme care must be exercised when select-
ing 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 fnish (some Fitting fnishes 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 conduc-
tive Hose. For other applications consult the individual catalog pages and the
appropriate industry or regulatory standards for proper selection.
