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 “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.
1.2 Fail-Safe: Hose, and 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 that is
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 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 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 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 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 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 require the
Hose and the Fitting 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 these 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 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 manufacturer 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 manufacturers 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 AGA Requirements 1-93, “Hoses for Natural Gas Vehicles and Fuel
Dispensers”. 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 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 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. Parker CNG Hose should not be used in confined
spaces or unventilated areas or areas exceeding 180°F. Final assemblies must be
tested for leaks. CNG Hose Assemblies should be tested on a monthly basis for
conductivity per AGA 1-93.
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.
•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, and no other Hose can be used for such in flight applications.
