Parker Safety Guide
For selecting and using Hose, Tubing, Fittings, and Related Accessories
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.
WARNING
:
Failure or improper selection or improper use of hose, tubing, assemblies, fittings, quick action couplings 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 power lines.
•
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.

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”, “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 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 provide 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, or 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 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.
•
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 to
, for telephone numbers of the
appropriate technical service department.

HOSE AND FITTINGS 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
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 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 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
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 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
