please refer to the bulletin of
the Parker Fluid Connectors
Group
It is the professed goal of the
Parker Polyflex Division to extend
and strengthen its position as
market leader in the field of ther-
moplastic hoses worldwide.
The integrated hose concept falls
within this framework.
In detail, this means an integrated
system for bulk hose, fittings, ma-
chinery, tools and accessories.
A fundamental part of this overall
concept is the safe manufacturing
of thermoplastic hose assemblies.
The machinery equipment sug-
gested by Parker Polyflex builds
the foundation of the certification
process of our distribution part-
ners. It ensures that each hose
workshop certified by Parker is
able to achieve a high quality lev-
el that reflects the quality stan-
dards of the hose and fitting com-
ponents in the finished hose as-
sembly and thus meets the guide-
lines defined by Parker Polyflex.
The Parker Polyflex Division
therefore actively supports the
distributor with information and
quotes from manufacturers of
tools and machinery needed to
properly set up the workshop.
Due to the complexity of the wide
range of applications and tasks, it
is nevertheless difficult to intro-
duce a universally valid standard
solution.
This bulletin gives an overview
of the most important steps a
new distributor has to take to be-
come a certified distributor. It
also shows the process for already
certified distributors pursuing re-
certification. Furthermore, the
process of the workshop certifi-
cation process through the stan-
dardized workshop evaluation
sheet is being explained.
It is an indispensable require-
ment to fulfill the stated criteria
in order to be able to permanent-
ly deliver quality products to our
joint customers.

Certification process
For potential new distributors of Parker Polyflex hose
assemblies
Steps to becoming a certified Parker distributor
In order to become a certified
Parker Polyflex distributor, the
Parker Polyflex Division in con-
junction with the respective
Country Sales Managers identifies
appropriate distributors for the
assembly of hoses for Hydraulic,
Water Jetting and Oil and Gas ap-
plications. After the initial process
of identifying potential new dis-
tributors has been completed and
the go ahead has been given by
all parties involved, the following
steps have to be taken to become
a certified distributor:
1. Preparation of business
plan
The potential distributor has
to prepare a business plan
and present as well as discuss
it with the respective Country
Sales Manager and the Parker
Polyflex Division. The follow-
ing key figures have to be in-
cluded in this business plan:
1.1 Clearly state the mar-
ket you are targeting and
with which Parker Poly-
flex products you want to
target it with. Prepare an
overview which hose types
and what quantities are to
be bought. An initial stock
order of of at least 70,000 $
has to be made.
1.2 State the market share /
potential of this market in
your country/area.
1.3 Show an overview of the
sales potential for the next
two years.
1.4 Specify what equipment
is currently available in
your workshop and what
needs to be bought in or-
der to qualify for certifica-
tion. The equipment and
facilities of the workshop
need to meet the required
Parker Polyflex standards,
which will be specified be-
low under 2.2 Workshop
requirements. The overall
aim is to build a fully func-
tional hose assembly unit.
Also, clearly state how the
production process of the
hose assemblies will take
place and how the differ-
ent facilities are arranged
for the assembly process.
The Sales Company of the
respective country will
check the equipment and
facilities, once the busi-
ness plan has been hand-
ed in and provide further
assistance with regard to
buying new equipment, if
needed.
1.5 Clearly state the total in-
vestment required to set
up the workshop for as-
sembly of Parker Polyflex
hoses
1.6 State what customers you
want to target and what
sales volume each of these
customers has, what prod-
ucts they would require
etc.
1.7 Specify how many people
in your company need to
be trained, the number of
staff and their qualifica-
tions.
2. Warehouse and Workshop
requirements
2.1 Warehouse requirements:
• The storage space for
hose and fittings needs to
be adequate
• Neat and tidy warehouse
environment
• A separate storage area
for doubtful, defective or
rejected parts should be
in place
2.2 Workshop requirements:
• Hose cutting equipment
for neat cuts including
length and measuring fa-
cility
• An extraction facility to
remove hose cutting par-
ticles would be recom-
mended, but is not man-
datory
• The saw blade used in
the hose cutting machine
needs to be smooth,
undamaged and non-
teethed
• A proper workbench and
vice need to be in place
• Marking equipment to
mark the ferrule with the
required details such as
name of manufacturer of
the hose assembly etc.,
needs to be in place
• A marking facility for the
hose insertion depth is
recommended, but not
mandatory
• A fitting insertion facil-
ity/hose assembly ma-
chine (for example the
SMM 100 which can be
purchased through Park-
er Polyflex) should be in
place
4. 4
• A mandatory require-
ment for the workshop is
a suitable crimper with
a crimp force of around
350 tons for general Oil
and Gas applications
and with a crimp force of
500 tons for the assembly
of the Black Eagle. For
the assembly of water
jetting and hydraulic ap-
plications a crimper with
a crimp force of 350 tons
is recommended to cov-
er the full range of hose
types and nominal diam-
eters for those applica-
tions.
• The sizes of the dies in-
tended to be used for the
assembly of hoses have
to be in line with the die
size stated in the assem-
bly instruction for the re-
spective hose type
• A full set of Go/No-Go
gauges has to be in place
as well as calipers
• A facility to drill relief
holes into the fitting
should be in place
• A test rig for static pres-
sure tests up to 1.5 times
of the at most needed
working pressure has to
be in place. For water jet-
ting a test rig for up to
5,000 bar ( 72,519 psi) is
recommended, to cover
the full Parker Polyflex
hose range. The test rig
also needs to be calibrat-
ed on a regular basis.
3. Training requirements
In order to receive training,
the potential distributor has to
commit to at least 2 employ-
ees being trained. The training
date and the location of train-
ing have to be discussed with
the respective Parker Polyflex
Division trainer. The Parker
Polyflex Division trainer will
also provide theoretical train-
ing prior to the practical as-
sembly training, if required by
the distributor. The theoreti-
cal and the assembly training
will be tailored to cater for the
needs of the participants be-
ing trained and the specific
requirements of the distribu-
tors´ workshop.
During the practical assem-
bly training, the trainer will
train the employees to inde-
pendently assemble the hose
types that are intended to be
assembled in the respective
distributor´s workshop. Fully
assembled samples of a vari-
ety of hose types will be made
during the training. After the
training, each participant
has to assemble a new hose
sample of each hose type as-
sembled during the training.
Each sample should be clearly
marked with the participant´s
name. For water jetting and
hydraulic applications only
one side of the respective hose
sample has to be fully assem-
bled, as no burst pressure test
has to be performed . Where
a DNV Type approval P-14038
from the DNV (Det Norske
Veritas, an independent foun-
dation with the purpose of
safeguarding life, property,
and the environment) or simi-
lar institutions is necessary,
burst pressure tests witnessed
by a DNV inspector or an in-
spector from another institu-
tion have to be performed at
the Hüttenfeld plant location.
Therefore, the samples sent in
have to be assembled on both
sides of the sample to ensure,
that a burst pressure test can
be performed.
The returned hose samples
have to be tested and exam-
ined, to verify that the hose
assemblies were performed
in line with the respective as-
sembly instruction.
Once all sent in hose samples
of the participant have been
approved, a certificate will be
issued.
This certificate will be valid for
a duration of two years.
The Parker Polyflex Division
also will provide the distribu-
tor with all the necessary pro-
cedures and safety instruc-
tions, including product and
procedure updates.

5. Re-certfication procedure
for employees and work-
shop
A few months before the cer-
tificates of the participants ex-
pire, the Parker Polyflex Divi-
sion will contact the distribu-
tor to arrange a training date
for re-certification, and if nec-
essary training for new em-
ployees, as it is prohibited to
assemble hose without proper
certification in place.
A renewal certificate for the
workshop can also be issued
for the duration of two years,
once the audit evaluation pro-
cess has been passed again
and all criteria are being met.
The Parker Polyflex Division
reserves the right to cancel
any certificates, if the distribu-
tor does not work and act in
line with the Parker Polyflex
procedures.
Please note that the certifi-
cate clearly specifies the hose
types/applications the em-
ployee is allowed to manufac-
ture. The certificate also clear-
ly states the company name of
the distributor and the loca-
tion.
Any changes of the before
mentioned parameters will
result in the certificate being
null and void. Meaning that
the certificate is only valid as
long as the employee is be-
ing employed in the compa-
ny stated on the certificate. It
cannot be transferred to an-
other company.
6. Access to assembly
instructions
Parker Polyflex will pro-
vide the distributor access
to sharepoint, a User ID and
password secured platform
where all assembly instruc-
tions for Hydraulic, Water Jet-
ting and Oil Gas applica-
tions are being stored. This
online tool ensures that the
distributor is able to access
the assembly instructions for
the respective hose types at all
times and that the latest ver-
sions are being used.
Furthermore, the assembly in-
structions should be available
as print outs in the workshop,
and it has to be checked on
a regular basis that the most
current ones are being used.
6. 6
Workshop certification process
for manufacturers of Parker Polyflex hose assemblies
Safety Instructions
1. Purpose
• To make sure that workshop
certifications are performed
according to standardized
tests and procedures. This is
being guaranteed by a stan-
dardized workshop evalua-
tion sheet, which documents
all the criteria a workshop
has to fulfill in order to be
certified by Parker Polyflex
for a duration of 2 years.
• Th e certification require-
ments are determined
in such a way that after
certification has been award-
ed, the employees trained
and certified by Parker Poly-
flex are able to assemble
hose assemblies according
to Parker Polyflex standards.
The equipment of the work-
shop and the manufacturing
process of hose assemblies
are being discussed between
the distribution partner and
Parker Polyflex.
2. Responsibilities
• It is the responsibility of
Parker Polyflex to perform
the workshop evaluation au-
dit together with a represen-
tative of the respective Sales
Company and the person in
charge of the audited work-
shop. The certification pro-
cess of workshop staff has to
be performed according to
requirements set by PFDE.
• It is the responsibility of
Parker Polyflex to issue the
workshop certificate and the
individual workshop staff
certificate once all require-
ments have been met.
3. Procedure
• Th e requirement criteria for
certification are explained
ideally to the hose assem-
bly manufacturer during a
plant inspection with the
Sales Company (preparatory
meeting).
• Th e workshop evaluation
audit will be performed at a
date and time arraged prior.
Hereby it is recommended,
to have the certification au-
dit on the same day the cer-
tification of employees takes
place.
• Th e audit results will be eval-
uated by Parker Polyflex in
liaison with the hose assem-
bly manufacturer.
• Th e hose assembly manu-
facturer will receive a de-
tailed audit report and will
be awarded the certificate if
the audit result is positive.
4. Validity period
• Th e workshop certificate
will be valid for a period
of two years after the first
certification has taken place.
• A new evaluation audit of
the workshop can take place
two years after the first cer-
tification. This certification
will also be valid for another
two years.
Flexible hoses are used to
transmit fluids, sometimes
at high pressures. The pow-
ergrip between the crimp fit-
ting and the hose is the criti-
cal zone in all flexible hose
connections. Only the use of
Parker components (hoses,
fittings and tool) designed to
be assembled by means of
the appropriate Parker tool-
ing, and full compliance with
the assembly instructions,
can guarantee safety and
conformity with standards.
Adherence to installation
recommendations and suit-
able maintenance also give a
guarantee for long life of the
flexible hose. Non-compliance
with these elementary rules
can lead to the rupture of a
flexible hose and cause con-
siderable damage and some-
times bodily injury.
7. 7
1. Storage and usage duration of hose assemblies
2. Material selection and verification
The storage space for hose and
fittings needs to be adequate and
a neat and tidy warehouse en-
vironment needs to be in place.
Further more a separate storage
place for doubtful, defective or
rejected parts needs to be inte-
grated into the warehouse. In this
separate storage place the parts
need to be clearly marked (each
batch/box/coil) with orange or
red labels.
Proper storage will maximize
hose shelf life. Improper storage,
mechanical damage and unac-
ceptable wear are the main rea-
sons for failure. Therefore, Parker
Polyflex thermoplastic tubes, hos-
es and hose assemblies should al-
ways be stored in such a manner
to protect them from degrading
factors. Extreme temperatures,
humidity, ozone, UV (daylight),
oils, solvents, corrosive liquids,
radioactivity etc. lead to a de-
crease of storage.
All customers deserve a quality
product. Initial visual inspection
of hose assembly components
must be performed. The following
criteria have to be checked:
Provided that original storage
containers are available compo-
nents should be stored there and
inventory should be rotated on a
first-in, first-out basis, to insure
that the products are exposed to
the shortest shelf time possible.
Storage conditions should be in
line with PFDE-ES39 (User manu-
al for the Application of Hose As-
semblies for High-Pressure Wa-
ter Jet Machines). Storage areas
are supposed to be relatively cool,
dark, dry and free from dirt, dust
and mold. Direct light from fluo-
rescent or mercury lamps should
be avoided and electronical
equipment should not be used.
Hose assemblies should be stored
stress-free and horizontal. When
stacking hose, the minimal bend
radius should not be underrun.
Furthermore, fittings should be
stored with protection caps to
avoid damage of the threads.
• Working pressure of the hose as-
sembly is in line with the pres-
sure of the pump
• No hose cover abrasion
• Fittings are not corroded
• Thread and sealing surface are
neither damaged nor dirty
• O-rings are available and not
damaged
The maximum storage time of
bulk hose is 10 years and that of
completed hose assemblies is up
to 2 years. If possible, storage of
hose assemblies should be avoid-
ed. The natural properties of the
hose materials cause a loss of
compression in the fitting, which
may lead to premature leakage of
the fitting. The usage of a hose as-
sembly is not limited by Parker,
however it should not exceed 6
years.
Tubes, hoses or hose assem-
blies that exceed the above men-
tioned storage period have to be
checked visually before usage
and serviceability has to be made
sure through a pressure test of 1.5
times working pressure (pressure
hold time at least 5 minutes).
Furthermore, proper drum and
handling equipment need to be
in place as well as a workbench
and vice. In addition, a hose reel
stand should be in place, but is
not mandatory.
Furthermore, it is strictly prohib-
ited to “mix and match” hose and
fittings. Only fittings defined in
the catalogue for the respective
hose type can be used.
8. 8
3. Cutting
4. Marking
This procedure is one of the criti-
cal steps of the assembly. Should
the cut not be precise and square,
this could compromise proper
insertion of the end fitting of the
hose and thus influence the qual-
ity of the hose assembly. A proper
measuring facility for cutting the
hose should also be in place.
Prior to cutting the hose it has to
be made sure that the part of the
hose that is being cut is wrapped
with at least two layers of fiber-re-
inforced tape, to prevent the rein-
forcement from flaring. An extrac-
tion facility to remove hose cut-
ting particles is recommended,
but not mandatory.
As an example for water jetting,
the marking of hose assemblies
has to be performed according
to the European DIN EN1829-2:
2012-02 and the following infor-
mation has to be included:
The hose has to be marked ex
works with information about the
manufacturer, max. working pres-
sure, article number, nominal di-
ameter, batch number and date
manufacture (quarter /year). Fur-
ther information can also be in-
cluded.
The cutting shall be performed
in a hose cutting machine that is
equipped with a smooth, undam-
aged and non-teethed saw blade.
It has to be made sure that the
hose cutting machine is in im-
maculate condition and calibrat-
ed on a regular basis.
For your safety:
• Keep your hands away from
the blade at all times
(150 mm min.)
• Disconnect the machine
from the electrical supply
network for all maintenance
work
The protective sleeve does not
have marking by default.
The ferrule is engraved with in-
formation about the manufac-
turer, max. working pressure, the
month/year of manufacture as
well as the norm “EN 1829-2” for
water jetting applications.

5. Crimping
6. Hydrostatic proof pressure test
The crimper has to be set-up with
the appropriate tools according to
Parker recommendations and
should be calibrated on a regular
basis. A die set storage has to be
allocated to the workshop crimp-
er, to allow for proper storage of
the equipment.
A strict procedure in line with the
respective assembly instruction
has to be ensured and the crimp
force of the crimper has to be ad-
equate for the to-be crimped
hose. Furthermore, the die size
stated in the assembly instruction
has to be used for the respective
hose type.
The dies used have to be faultless
and should not be worn out.
The insertion depth has to be
marked, preferably with a proper
tool and the fiber-reinforced tape
has to be taken off, prior to crimp-
ing the fitting. While some
fittings can be applied by hand
and the use of a rubber mallet, it
is necessary for some hose types
to apply the fittings with a hose
assembly machine.
For example the SMM 100 hose
assembly machine that is being
sold via Parker.
For pressures over 690 bar work-
ing pressure the safety and func-
tionality of the hose assembly
has to be checked through a final
pressure test.
The test rig should allow a pres-
sure of up to 5,000 bar (72,519
psi) to cover the full range of hose
types.
For water jetting applications a
dynamic pressure test with the
check mode X-Y-X has to be per-
formed. X stands for an increase
of pressure from 0 bar to 1.5 times
the working pressure of the re-
spective hose.
The bore of the nipple has to be
checked prior to crimping.
Furthermore, the adjusted crimp
force has to be checked with the
actual crimp force and the crimp-
ing procedure has to be done ac-
cording to the assembly instruc-
tion for the respective hose type.
It has to be made sure that the fit-
ting is crimped over its full length
and that a round smooth appear-
ance is achieved by turning the
hose slightly around while crimp-
ing.
When crimping, conicity and
ovality of the crimp have to be
checked. Subsequent to crimping,
the crimped hose assembly has to
be checked with gauges and cali-
per, as defined in the respective
assembly instruction, for speci-
fied nipple collapse and correct fit
of the fitting. The no-go gauge has
to stop the middle of the nipple
tail and the go gauge has to slide
through. It has to be made sure
that gauges For some hose types
it is necessary to drill a relief hole
into the fitting after crimping. The
information for the respective
measure can be taken out of the
A pressure hold time of 1 minute
has to be adhered to. Y stands for
5 pressure changes from 0 bar up
to the respective working pres-
sure, whereat no pressure hold
time is necessary. After the pres-
sure test the hose has to be blown
out with pressurized air. For other
hose types please refer to the in-
dividual assembly instruction.
The test rig unit has to be calibrat-
ed on a regular basis to ensure ac-
curate pressure test results.
assembly instruction.
For your safety:
• Keep your hands far away
from the crimping head at
all times
• Switch off the machine en-
gine, if you change the dies
manually (segment by seg-
ment)
• Disconnect the machine-
from the electrical supply
network for all maintenance
