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, ft-
tings, 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.

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 “HoseAssemblies”. 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 consid-
ered for use. Parker publications are available
. SAE J1273
and ISO 17165
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. 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
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. 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 fnal selection of the Products.
• Assuring that the user’s requirements are met and that the applica-
tion presents no health or safety hazards.
• Providing all appropriate health and safety warnings on the equip-
ment on which the Products 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 Products being considered or used, or call 1 800
CPARKER, or go t
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 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 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 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 conductive
Hose. For other applications consult the individual catalog pages and the ap-
propriate 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 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 assem-
blies comply with the requirements of ANSI/IAS NGV 4.2-1999; CSA 12.52-M99,
“Hoses for Natural Gas Vehicles and Dispensing Systems”
his
Hose is labeled “Electrically Conductive for CNG Use” on its layline and packag-
ing. 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 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 HoseAssemblies 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. Aero-
space 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.
Safety Guide
• 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.
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.
