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 “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, 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 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 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 www.parker.com, for telephone numbers of the appropriate technical service department.
2.0 HOSE AND FITTINGS 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 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 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 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 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 maximum working pressures of the Hose and the Fittings used. Surge pressures or
peak transient pressures in the system must be below the published maximum working pressure for the Hose. Surge pressures and peak pressures can usually only be determined
by sensitive electrical instrumentation that measures and indicates pressures at millisecond intervals. Mechanical pressure gauges indicate only average pressures and cannot
be used to determine surge pressures or peak transient pressures. Published burst pressure ratings for Hose is for manufacturing test purposes only and is no indication that the
Product can be used in applications at the burst pressure or otherwise above the published maximum recommended working pressure.
2.3 Suction: Hoses used for suction applications must be selected to insure that the Hose will withstand the vacuum and pressure of the system. Improperly selected Hose may
collapse in suction application.
2.4 TemperaturE: Be certain that fuid and ambient temperatures, both steady and transient, do not exceed the limitations of the Hose. Temperatures below and above the
