recommended limit can degrade Hose to a point where a failure may occur and release fuid. Properly insulate and protect the Hose Assembly when routing near hot objects (e.g.
manifolds). Do not use any Hose in any application where failure of the Hose could result in the conveyed fuids (or vapors or mist from the conveyed fuids) contacting any open
fame, molten metal, or other potential fre ignition source that could cause burning or explosion of the conveyed fuids or vapors.
2.5 Fluid Compatibility: Hose Assembly selection must assure compatibility of the Hose tube, cover, reinforcement, and Fittings with the fuid media used. See the fuid
compatibility chart in the Parker publication for the product being considered or used. This information is offered only as a guide. Actual service life can only be determined by
the end user by testing under all extreme conditions and other analysis.
Hose that is chemically compatible with a particular fuid must be assembled using Fittings and adapters containing likewise compatible seals.
2.6 Permeation: Permeation (that is, seepage through the Hose) will occur from inside the Hose to outside when Hose is used with gases, liquid and gas fuels, and refrigerants
(including but not limited to such materials as helium, diesel fuel, gasoline, natural gas, or LPG). This permeation may result in high concentrations of vapors which are
potentially fammable, explosive, or toxic, and in loss of fuid. Dangerous explosions, fres, and other hazards can result when using the wrong Hose for such applications. The
system designer must take into account the fact that this permeation will take place and must not use Hose if this permeation could be hazardous. The system designer must take
into account all legal, government, insurance, or any other special regulations which govern the use of fuels and refrigerants. Never use a Hose even though the fuid compatibility
is acceptable without considering the potential hazardous effects that can result from permeation through the Hose Assembly.
Permeation of moisture from outside the Hose to inside the Hose will also occur in Hose assemblies, regardless of internal pressure. If this moisture permeation would have
detrimental effects (particularly, but not limited to refrigeration and air conditioning systems), incorporation of suffcient drying capacity in the system or other appropriate system
safeguards should be selected and used.
2.7 Size: Transmission of power by means of pressurized fuid varies with pressure and rate of fow. The size of the components must be adequate to keep pressure losses to a
minimum and avoid damage due to heat generation or excessive fuid velocity.
2.8 Routing: Attention must be given to optimum routing to minimize inherent problems (kinking or fow restriction due to Hose collapse, twisting of the Hose, proximity to
hot objects or heat sources). For additional routing recommendations see SAE J1273 and ISO 17165-2. Hose Assemblies have a fnite life and if possible, should be installed in
a manner that allows for ease of inspection and future replacement. Rubber Hose because of its relative short life, should not be used in residential and commercial buildings for
HVAC (heating, ventilating and air conditioning) applications.
2.9 Environment: Care must be taken to insure that the Hose and Fittings are either compatible with or protected from the environment (that is, surrounding conditions) to which
they are exposed. Environmental conditions including but not limited to ultraviolet radiation, sunlight, heat, ozone, moisture, water, salt water, chemicals and air pollutants can
cause degradation and premature failure.
2.10 Mechanical Loads: External forces can signifcantly reduce Hose life or cause failure. Mechanical loads which must be considered include excessive fexing, twist, kinking,
tensile or side loads, bend radius, and vibration. Use of swivel type Fittings or adapters may be required to insure no twist is put into the Hose. Unusual applications may require
special testing prior to Hose selection.
2.11 Physical Damage: Care must be taken to protect Hose from wear, snagging, kinking, bending smaller that minimum bend radius and cutting, any of which can cause
premature Hose failure. Any Hose that has been kinked or bent to a radius smaller than the minimum bend radius, and any Hose that has been cut or is cracked or is otherwise
damaged should be removed and discarded.
2.12 Proper End Fitting: See instructions 3.2 through 3.5. These recommendations may be substantiated by testing to industry standards such as SAE J517 for hydraulic
applications, or MIL-A-5070, AS1339, or AS3517 for Hoses from Parker’s Stratofex Products Division for aerospace applications.
2.13 Length: When establishing a proper Hose length, motion absorption, Hose length changes due to pressure, and Hose and machine tolerances and movement must be
considered.
2.14 Specifcations and Standards: When selecting Hose and Fittings, government, industry, and Parker specifcations and recommendations must be reviewed and followed as
applicable.
2.15 Hose Cleanliness: Hose components may vary in cleanliness levels. Care must be taken to insure that the Hose Assembly selected has an adequate level of cleanliness for
the application.
2.16 Fire Resistant Fluids: Some fre resistant fuids that are to be conveyed by Hose require use of the same type of Hose as used with petroleum base fuids. Some such fuids
require a special Hose, while a few fuids will not work with any Hose at all. See instructions 2.5 and 1.5. The wrong Hose may fail after a very short service. In addition, all
liquids but pure water may burn fercely under certain conditions, and even pure water leakage may be hazardous.
2.17 Radiant Heat: Hose can be heated to destruction without contact by such nearby items as hot manifolds or molten metal. The same heat source may then initiate a fre. This
can occur despite the presence of cool air around the Hose.
2.18 Welding or Brazing: When using a torch or arc welder in close proximity to hydraulic lines, the hydraulic lines should be removed or shielded with appropriate fre resistant
materials. Flame or weld spatter could burn through the Hose and possibly ignite escaping fuid resulting in a catastrophic failure. Heating of plated parts, including Hose Fittings
and adapters, above 450°F (232°C) such as during welding, brazing or soldering may emit deadly gases.
2.19 Atomic Radiation: Atomic radiation affects all materials used in Hose assemblies. Since the long-term effects may be unknown, do not expose Hose assemblies to atomic
radiation.
2.20 Aerospace Applications: The only Hose and Fittings that may be used for in-fight aerospace applications are those available from Parker’s Stratofex Products Division. Do
not use any other Hose or Fittings for in-fight applications. Do not use any Hose or Fittings from Parker’s Stratofex Products Division with any other Hose or Fittings, unless
expressly approved in writing by the engineering manager or chief engineer of Stratofex Products Division and verifed by the user’s own testing and inspection to aerospace
industry standards.
2.21 Unlocking Couplings: Ball locking Couplings or other Fittings with quick disconnect ability can unintentionally disconnect if they are dragged over obstructions, or if the
sleeve or other disconnect member is bumped or moved enough to cause disconnect. Threaded Fittings should be considered where there is a potential for accidental uncoupling.
3.0 HOSE AND FITTINGS ASSEMBLY AND INSTALLATION INSTRUCTIONS
3.1 Component Inspection: Prior to assembly, a careful examination of the Hose and Fittings must be performed. All components must be checked for correct style, size,
catalog number, and length. The Hose must be examined for cleanliness, obstructions, blisters, cover looseness, kinks, cracks, cuts or any other visible defects. Inspect the Fitting
and sealing surfaces for burrs, nicks, corrosion or other imperfections. Do NOT use any component that displays any signs of nonconformance.
3.2 Hose and Fitting Assembly: Do not assemble a Parker Fitting on a Parker Hose that is not specifcally listed by Parker for that Fitting, unless authorized in writing by
the engineering manager or chief engineer of the appropriate Parker division. Do not assemble a Parker Fitting on another manufacturer’s Hose or a Parker Hose on another
manufacturer’s Fitting unless (i) the engineering manager or chief engineer of the appropriate Parker division approves the Assembly in writing or that combination is expressly
approved in the appropriate Parker literature for the specifc Parker product, and (ii) the user verifes the Assembly and the application through analysis and testing. For Parker
Hose that does not specify a Parker Fitting, the user is solely responsible for the selection of the proper Fitting and Hose Assembly procedures. See instruction 1.4.
To prevent the possibility of problems such as leakage at the Fitting or system contamination, it is important to completely remove all debris from the cutting operation before
installation of the Fittings. The Parker published instructions must be followed for assembling the Fittings on the Hose. These instructions are provided in the Parker Fitting
catalog for the specifc Parker Fitting being used, or by calling 1-800-CPARKER, or at www.parker.com.
3.3 Related Accessories: Do not crimp or swage any Parker Hose or Fitting with anything but the listed swage or crimp machine and dies in accordance with Parker published
instructions. Do not crimp or swage another manufacturer’s Fitting with a Parker crimp or swage die unless authorized in writing by the engineering manager or chief engineer of
the appropriate Parker division.
3.4 Parts: Do not use any Parker Fitting part (including but not limited to socket, shell, nipple, or insert) except with the correct Parker mating parts, in accordance with Parker
published instructions, unless authorized in writing by the engineering manager or chief engineer of the appropriate Parker division.
3.5 Field Attachable/Permanent: Do not reuse any feld attachable Hose Fitting that has blown or pulled off a Hose. Do not reuse a Parker permanent Hose Fitting (crimped or
swaged) or any part thereof. Complete Hose Assemblies may only be reused after proper inspection under section 4.0. Do not assemble Fittings to any previously used hydraulic
Hose that was in service, for use in a fuid power application.
3.6 Pre-Installation Inspection: Prior to installation, a careful examination of the Hose Assembly must be performed. Inspect the Hose Assembly for any damage or defects.
DO NOT use any Hose Assembly that displays any signs of nonconformance.
3.7 Minimum Bend Radius: Installation of a Hose at less than the minimum listed bend radius may signifcantly reduce the Hose life. Particular attention must be given to
preclude sharp bending at the Hose to Fitting juncture. Any bending during installation at less than the minimum bend radius must be avoided. If any Hose is kinked during
installation, the Hose must be discarded.
3.8 Twist Angle and Orientation: Hose Assembly installation must be such that relative motion of machine components does not produce twisting.
3.9 Securement: In many applications, it may be necessary to restrain, protect, or guide the Hose to protect it from damage by unnecessary fexing, pressure surges, and contact
with other mechanical components. Care must be taken to insure such restraints do not introduce additional stress or wear points.
