HOSE SELECTION & SERVICE LIFE RECOMMENDATIONS
INFORMATION - HOSE
Hydraulic hose (and hose assemblies) have a nite life span that is dependent upon the actual
operating conditions the assembly is subjected to.
An effective way to remember hose selection criteria is to remember the word FACTOR. FACTOR is
an acronym for the following:
F = Fluid (or material) to be conveyed
A = Application
C = Conditions
T = Temperature
O = Operating pressure
R = Rates of ow (volume and velocity)
1. Fluid (or material) to be conveyed. Hose selection must ensure compatibility of the hose
tube (liner) and outer cover with the oil, chemical or gas to be conveyed. A chemical resistance table
specic to Gates rubber compounds can be found in this section. Similar care to ensure compatibil-
ity should be taken when specifying end connections (hosetails and adaptors), especially those that
contain o-rings.
2. Application. The determination of how the hydraulic hose or hose assembly will be used.
Questions that may need to be answered to ensure correct hose selection could include: What is the
suitable hose construction? What type of equipment is it used on? What are the end connections?
Are there applicable Government or Industry standards to be satised?
3. Conditions. This criteria can be viewed as an extension of application; the determination of
where the hose or hose assembly will be used. Questions that may need to be answered to ensure
correct hose selection could include; What are the environmental conditions the hose will be used in?
Does the hose require a special cover or armour? Are there unusual mechanical loads or excessive
movement? What are the routing requirements? What are the required lengths and bend radius to
satisfy those routing requirements? (Further data regarding Hose Installation Recommendation can
be found in this section.)
4. Temperature. Hose selection is determined by two variables of temperature; the ambient
(external) temperature and the uid/material (internal) temperature. The hose should not be exposed
to internal or external temperatures which exceed the manufacturer’s stated maximum and minimum
limits. Both continual and intermittent temperatures must be accommodated within the recommend-
ed limits. Extra care must be taken when specifying hoses that are routed near to (or terminate on)
hot components such as engine manifolds.
5. Operating Pressure. The pressure in a hydraulic system should not exceed the stated hose
working pressure at any time. System pressure spikes and surges must be considered and accom-
modated within the stated working pressure limits. Minimum burst pressures are reference pres-
sures, and are intended for destructive testing and design purposes only.

HOSE SELECTION & SERVICE LIFE RECOMMENDATIONS (cont’d)
INFORMATION - HOSE
6. Rates of Flow. Hose Internal Diameter can be determined using the Nomographic Chart
found in this section. The correct hose I.D. must be selected for the ow volume required. Too small
an I.D. for a given volume will result in pressure drop, heat generation, uid turbulence and possible
internal tube damage. If in doubt, select the next size up.
Exposure of hose or hose assemblies to operating conditions which exceed recommended or stated
limits will signicantly reduce the expected service life. If in doubt, over-specify hose assemblies to
ensure as much safety margin on the recommended limits as possible.
Extracts from SAE J1273 DEC2002: Recommended Practices for Hydraulic Hose Assemblies
1. Scope—SAE J1273 provides guidelines for selection, routing, fabrication, installation, replace-
ment, maintenance, and storage of hose and hose assemblies for uid-power systems. Many of
these SAE Recommended Practices also may be suitable for other hoses and systems.
5. Hose Selection and Routing —A wide variety of interacting factors inuence hose service life
and the ability of each uid-power system to operate satisfactorily, and the combined effects of these
factors on service life are often unpredictable. Therefore, these documents should not be construed
as design standards. For applications outside the specications in SAE J517, SAE J514, or other
relevant design standards, performance of hose assemblies should be determined by appropriate
testing. Carefully analyze each system. Then design routings and select hose and related compo-
nents to meet the system-performance and hose-service-life requirements, and to minimize the risks
of personal injury and/or property damage. Consider the following factors:
5.1 System Pressures—Excessive pressure can accelerate hose assembly failure. Analyze the
steady-state pressures, and the frequency and amplitude of pressure surges, such as pulses and
spikes. These are rapid and transient rises in pressure which may not be indicated on many common
pressure gauges and can be identied best on high-frequency-response electronic measuring instru-
ments.
For maximum hose service life, hose selection should be based on a system pressure, including
surges, that is less than the hose maximum working pressure. Hose may be used above its maxi-
mum working pressure where reduced life expectancy is acceptable. SAE J1927 provides one
method to help predict wire-reinforced hose service life for a given hydraulic application, where the
surge pressure peaks vary, and/or the highest pressure peaks occur infrequently.
5.2 Suction—For suction applications, such as inlet ow to pumps, select hose to withstand both the
negative and positive pressures the system imposes on the hose.
5.3 External Pressure—In certain applications, such as in autoclaves or under water, the external
environmental pressures may exceed the uid pressure inside the hose. In these applications, con-
sider the external pressures, and if necessary, consult the manufacturers.
5.4 Temperature—Exceeding hose temperature ratings may signicantly reduce hose life. Select
hose so the uid and ambient temperatures, both static and transient, fall within the hose ratings. The
effects of external heat sources should not raise the temperature of the hose above its maximum op-
erating temperature. Select hose, heat shields, sleeving, and other methods for these requirements,

and route or shield hose to avoid hose damage from external heat sources.
5.5 Permeation—Permeation, or effusion, is seepage of uid through the hose. Certain materials in
hose construction are more permeable than others. Consider the effects of permeation when select-
ing hose, especially with gaseous uids. Consult the hose and uid manufacturers for permeability
information.
5.6 Hose-Material Compatibility—Variables that can affect compatibility of system uids with hose
materials include, but are not limited to:
a. Fluid pressure
b. Temperature
c. Concentration
d. Duration of exposure
Because of permeation (see 5.5), consider compatibility of system uids with the hose, tube, cover,
reinforcement, and ttings. Consult the uid and hose manufacturers for compatibility information.
NOTE— Many uid/elastomer compatibility tables in manufacturers’ catalogs show ratings based onuids at 21 °C, room temperature. These ratings may change at other temperatures. Carefully read
the notes on the compatibility tables, and if in doubt, consult the manufacturer.
5.7 Environment—Environmental conditions can cause hose and tting degradation. Conditions to
evaluate include, but are not limited to:
a. Ultraviolet light
b. Salt water
c. Air pollutants
d. Temperature (see 5.4)
e. Ozone
f. Chemicals
g. Electricity
h. Abrasion
If necessary, consult the manufacturers for more information.
5.8 Static-Electric Discharge—Fluid passing through hose can generate static electricity resulting in
static-electric discharge. This may create sparks that can puncture hose. If this potential exists, select
hose with suf cient conductivity to carry the static-electric charge to ground.
5.9 Sizing—The power transmitted by pressurized uid varies with pressure and rate of ow. Select
hose with adequate size to minimize pressure loss, and to avoid hose damage from heat generation
or excessive velocity. Conduct calculations, or consult the manufacturers for sizing at ow velocities.
5.10 Unintended Uses—Hose assemblies are designed for the internal forces of conducted uids.
Do not pull hose or use it for purposes that may apply external forces for which the hose or ttings
were not designed.
5.11 Specications and Standards—When selecting hose and ttings for specic applications, refer
to applicable government, industry, and manufacturer’s specications and standards.

INFORMATION - HOSE
5.12 Unusual Applications—Applications not addressed by the manufacturer or by industry stan-
dards may require special testing prior to selecting hose.
5.13 Hose Cleanliness—The cleanliness requirements of system components, other than hose, will
determine the cleanliness requirements of the application. Consult the component manufacturers’
cleanliness information for all components in the system. Hose assemblies vary in cleanliness levels;
therefore, specify hose assemblies with adequate cleanliness for the system.
5.14 Hose Fittings—Selection of the proper hose ttings for the hose and application is essential for
proper operation and safe use of hose and related assembly equipment. Hose ttings are qualied
with the hose. Therefore, select only hose ttings compatible with the hose for the applications.
Improper selection of hose ttings or related assembly equipment for the application can result in
injury or damage from leaks, or from hose assemblies blowing apart (see 4.2, 6.2, 6.3, and 6.4).
5.15 Vibration—Vibration can reduce hose service life. If required, conduct tests to evaluate the fre-
quency and amplitude of system vibration. Clamps or other means may be used to reduce the effects
of vibration. Consider the vibration requirements when selecting hose and predicting service life.
5.16 Hose Cover Protection—Protect the hose cover from abrasion, erosion, snagging, and cutting.
Special abrasion-resistant hoses and hose guards are available for additional protection. Route hose
to reduce abrasion from hose rubbing other hose or objects that may abrade it.
5.17 External Physical Abuse—Route hose to avoid:
a. Tensile loads
b. Side loads
c. Flattening
d. Thread damage
e. Kinking
f. Damage to sealing surfaces
g. Abrasion
h. Twisting
5.18 Swivel-Type Adapters—Swivel-type ttings or adapters do not transfer torque to hose while be-
ing tightened. Use these as needed to prevent twisting during installation.
5.19 Live Swivels—If two components in the system are rotating in relation to each other, live swiv-
els may be necessary. These connectors reduce the torque transmitted to the hose.
5.20 Slings and Clamps—Use slings and clamps to support heavy or long hose and to keep it away
from moving parts. Use clamps that prevent hose movement that will cause abrasion.
5.21 Minimum Bend Radius—The minimum bend radius is dened in SAE J343 and is specied in
other SAE standards and hose manufacturer’s product literature. Routing at less than minimum bend
radius may reduce hose life. Sharp bending at the hose/tting juncture may result in leaking, hose
rupturing, or the hose assembly blowing apart (see 4.2)
5.22 Elbows and Adapters—In special cases, use elbows or adapters to relieve hose strain.
5.23 Lengths—Unnecessarily long hose can increase pressure drop and affect system performance.

HOSE SELECTION & SERVICE LIFE RECOMMENDATIONS (cont’d)
INFORMATION - HOSE
When pressurized, hose that is too short may pull loose from its ttings, or stress the tting connec-
tions, causing premature metallic or seal failures. When establishing hose length, use the following
practices:
5.23.1 MOTION ABSORPTION—Provide adequate hose length to distribute movement and prevent
bends smaller than the minimum bend radius.
5.23.2 HOSE AND MACHINE TOLERANCES—Design hose to allow for changes in length due to
machine motion and tolerances.
5.23.3 HOSE LENGTH CHANGE DUE TO PRESSURE—Design hose to accommodate length
changes from changing pressures. Do not cross or clamp together high- and low-pressure hoses.
The difference in length changes could wear the hose covers.
5.24 Hose Movement and Bending—Hose allows relative motion between system components.
Analyze this motion when designing hose systems. The number of cycles per day may signicantly
affect hose life. Also avoid multiple planes of motion and twisting motion. Consider the motion of the
hose when selecting hose and predicting service life. In applications that require hose to move or
bend, use these practices:
5.24.1 BEND IN ONLY ONE PLANE TO AVOID TWISTING
5.24.2 PREVENT HOSE BENDING IN MORE THAN ONE PLANE—If hose follows a compound
bend, couple it into separate segments, or clamp it into segments that ex in only one plane.
7. Hose Installation and Replacement —Use the following practices when installing hose assem-
blies in new systems or replacing hose assemblies in existing systems:
7.1 Pre-Installation Inspection—Before installing hose assemblies, examine:
a. Hose length and routing for compliance with original design
b. Assemblies for correct style, size, length, and visible nonconformities
c. Fitting sealing surfaces for burrs, nicks, or other damage
NOTE— When replacing hose assemblies in existing systems, verify that the replacement is of equal
quality to the original assembly.
7.2 Handling During Installation—Handle hose with care during installation. Kinking hose, or bend-
ing at less than minimum bend radius may reduce hose life. Avoid sharp bending at the hose/tting
juncture (see 5.21).
7.3 Twist Angle and Orientation—Pressure applied to a twisted hose may shorten the life of the
hose or loosen the connections. To avoid twisting, use the hose lay line or marking as a reference.
7.4 Securement and Protection—Install necessary restraints and protective devices. Determine that
such devices do not create additional stress or wear points.
7.5 Routing—Review proper routing practices provided in Section 5 and make appropriate correc-
tions to obtain optimum performance.

7.6 Assembly Torque—The connection end of a hose tting is normally threaded to obtain a tight
pressure seal when attached to a port, an adapter, or another tting. Sometimes bolts or screws pro-
vide the threaded connection. Each size and type of connection requires different torque values, and
these may vary due to type of material or exterior coating.
Follow appropriate torquing instructions to obtain a proper pressure seal without over-torquing. A
properly calibrated torque wrench should be used to tighten each connection, except when the manu-
facturer species tightening a specied number of hex at turns beyond nger tight to obtain a seal.
7.7 System Checkouts—In hydraulic or other liquid systems, eliminate all air entrapment after com-
pleting the installation. Follow manufacturers’ instructions to test the system for possible malfunctions
and leaks.
7.7.1 TO AVOID INJURY DURING SYSTEM CHECKOUTS:
a. Do not touch any part of the system when checking for leaks (see 4.1).
b. Stay out of potentially hazardous areas while testing hose systems (see Section 4).
c. Relieve system pressure before tightening connections.
8. Maintenance Inspection—A hose and tting maintenance program may reduce equipment down-
time, maintain peak operating performance, and reduce the risk of personal injury and/or property
damage. The user should design and implement a maintenance program that suits the specic ap-
plication and each specic hose in that application.
8.1 Inspection Frequency—Evaluate factors such as the nature and severity of the application, past
history, and manufacturers’ information to establish the frequency of visual inspections and functional
tests.
8.2 Visual Inspection (Hose and Fittings)—Visually inspect hose and ttings for:
a. Leaks at hose tting or in hose
b. Damaged, cut, or abraded cover
c. Exposed reinforcement
d. Kinked, crushed, attened, or twisted hose
e. Hard, stiff, heat cracked, or charred hose
f. Blistered, soft, degraded, or loose cover
g. Cracked, damaged, or badly corroded ttings
h. Fitting slippage on hose
i. Other signs of signicant deterioration
If any of these conditions exist, evaluate the hose assemblies for correction or replacement.
8.3 Visual Inspection (All Other Components)—When visually inspecting hose and ttings, inspect
for related items including:
a. Leaking ports
b. Damaged or missing hose clamps, guards, or shields
c. Excessive dirt and debris around hose
d. System uid: level, type, contamination, condition, and air entrainment
If any of these are found, address them appropriately.

8.4 Functional Test—Functional tests determine if systems with hose are leak free and operating
properly. Carry out functional tests per information from equipment manufacturers.
9. Hose Storage—Age control and the manner of storage can affect hose life. Use the following
practices when storing hose.
9.1 Age Control—Maintain a system of age control to determine that hose is used before its shelf
life has expired. Shelf life is the period of time when it is reasonable to expect the hose to retain full
capabilities for rendering the intended service.
Store hose in a manner that facilitates age control and rst-in, rst-out usage based on manufactur-
ing date on hose or hose assembly. Per SAE J517:
a. Shelf life of rubber hose in bulk form, or in hose assemblies passing visual inspection and
proof test, is forty quarters (ten years) from the date of vulcanization.
b. Shelf life of thermoplastic and polytetrauoroethylene hose is considered to be unlimited.
