1.0 GENERAL INSTRUCTIONS
1.1 Scope: This safety guide provides instructions for selecting and using
(including assembling, installing, and maintaining) these Products. For con-
venience, all rubber and/or thermoplastic products commonly called “hose”
or “tubing” are called “Hose” in this safety guide. Metallic tube or pipe are
called “tube”. All assemblies made with Hose are called “Hose Assemblies”.
All assemblies made with Tube are called “Tube Assemblies”.
All products commonly called “fittings”, “couplings” or “adapters” are called
“Fittings”. Valves are fluid system components that control the passage
of luid. Related accessories are ancillary devices that enhance or monitor
performance including crimping, flaring, flanging, presetting, bending, cut-
ting, deburring, swaging machines, sensors, tags, lockout handles, spring
guards and associated tooling. 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 www.parker.com. SAE J1273 (www.sae.org)
and ISO 17165-2 (www.ansi.org) also provide recommended practices for
hydraulic Hose Assemblies, and should be followed.
1.2 Fail-Safe: Hose, Hose Assemblies, Tube, Tube 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, Hose Assembly,
Tube, Tube 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, Tube and Fitting products. Do not
select or use Parker Hose, Tube 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, Tube and Fittings. Parker does not represent or war-
rant that any particular Hose, Tube 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.
• Following the safety guide for Related Accessories and being trained to
operate Related Accessories.
• Providing all appropriate health and safety warnings on the equipment on
which the Products are used.
• Assuring compliance with all applicable government and industry stan-
dards.
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 tec hnical service department.

HOSE, TUBE & 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, Tube and Fittings for these or any other applications
in which electrical conductivity or nonconductivity is a factor.
The electrical conductivity or nonconductivity of Hose, Tube 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 electri-
cally 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.
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 non-
conductive, including but not limited to applications near high voltage elec-
tric 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, Tube 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 lim-
ited to applications near high voltage electric lines or dense magnetic fields,
unless (i) the application is expressly approved in the Parker technical pub-
lication 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, Tube 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 con-
nected 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. All hoses that convey fuels must be
grounded.
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;CSA 12.52, “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
