KEY FEATURES
Reference series on the agriculture market
Simple connection and disconnection by pulling back the
sleeve
Positive, quick connection of the male into the female by
the locking ball system
PLUS PERFORMANCES
Hardened male nipple and sleeve to withstand the brinelling effect of locking balls under pressure Hardened
poppet valve to increase service life against wear
Improved resistance against pressure impulses, due to increased thickness of Back-up Ring

MATERIAL: Female and male couplings in steel, with some hardened areas,
in correspondence to the most stressed points. Carbonitrited
valve, springs in C98 steel, seals in NBR (others materials on
request) and Back-up Ring in PTFE.
WORKING TEMPERATURE: -30°C up to +110°C / -22°F up to +230°F
(for other temperatures, the coupling may be assembled with
the specific seals).
SAFETY FACTOR: 1:4 for dynamic pressures and 1:2 for static pressures.
IMPULSE PRESSURES: 100.000 cycles at 133% of the rated one (freq. 1Hz).
TEST SPECIFICATIONS: ISO 7241-2.

MATERIAL: Female couplings in steel with some hardened areas in
correspondence to the most stressed points. Male couplings
in high grade carbon steel hardened. High-resistance latching
balls, springs in C98 steel, seals in NBR and Back-up Ring in
PTFE.
WORKING TEMPERATURE: -22°F up to +230°F -30°C up to +110°C
(for other temperatures the coupling is assembled with the specified seals).
SAFETY FACTOR: 1:4 for dynamic pressures and 1:2 for static ones.
IMPULSE PRESSURES: 100.000 cycles at 133% of the rated one (freq. 1Hz).

KEY FEATURES
Screw-type couplings specially designed for heavy duty
applications, such as hammers attachments, rock crushers,
etc.
Thanks to strengthen internal components this series is
high resistant against backflow, flow impulses and peaks,
pressure impulses, vibration and hoses bending
Connection and disconnection is made by screwing the
sleeve, also possible with rated pressure in the line

WARNINGS
PRESSUREFLUIDS
A quick coupling has to fit both the pressure and the flow rate of
each application. Always check the compatibility between the rated
performance of the coupling and the maximum system pressure.
The quick coupling pressure must be equal or greater than the
maximum pressure of the system. With many couplings connection
and disconnection must be carried out without any pressure in the
line. If it is not possible to decrease the pressure to zero, please use
specific quick couplings that are connectable under pressure. If any
residual pressures remains connection may still be difficult. Decrease
completely the system pressure to unlock the valves. Avoid using tools.
FLUIDS
Before each application, check the compatibility between the fluids
and the quick coupling materials or seals.
HOSE INSTALLATION GUIDE
Avoid to twist the hose assembly. During installation avoid moving parts that can cause twisting effects
on the hose assemblies (fig.1).
Use proper fittings to avoid tight bend radius. Do not start hose bending closer than 1,5 time “d” to the
ferrule (fig. 2).
Avoid interference with objects that can cause abrasion or damage to the hose. On flexing applications,
pay particular attention to avoid tensile stress or abrasion (fig. 3).
The hydraulic hoses of the Manuli product range are not designed for immersion in the service fluid. This
type of special applications should be avoided or carefully studied.
For detailed information concerning the recommended practices for hydraulic
hose assemblies, please refer to SAE J1273. This document should be used as
guide when selecting, routing, fabricating, installing, replacing, maintaining
and storing hose for hydraulic systems.
TEMPERATURE
Verify the temperature in use requested by each single application.
ENVIRONMENTAL CONDITIONS
The environmental conditions may damage the quick couplings:
remark the action of chemicals, UV radiations and salt waters.
PRECAUTIONS
Before connecting, clean carefully the insert, in order to avoid the
wear of the seals. Use all the precautions to preserve the quick
couplings as long as possible, such as caps and plugs when they are
disconnected. Avoid the falling on the ground of the quick couplings.
Try to immediately replace all the damaged spare parts (O-Rings and
Back-up Rings), with the specific kits in use. Check regularly, after
each individual application, the quick couplings, in order to detect any
visible crack, leakage, damage or corrosion result.

PRODUCT SELECTION
The foregoing description of the Manuli ® hoses,
connectors, hose assemblies and hose protections,
manufactured by Manuli Rubber Industries and
subsidiaries, and the general installation instructions are
provided as information to be considered when selecting
hose, connectors, hose assemblies and hose protections
for a particular application.
Additional factors which must be considered in selecting
proper hoses, connectors, hose assemblies and hose
protections for any particular application include hose
size, hose length, involved fluids, environment and
operating temperatures, system operating pressures,
static head pressures and installation design for the
application. Failure to consider all material factors in
selecting hoses, connectors, hose assemblies and hose
protections for a particular application can result in
reducing the hose assembly life or other failures which
can result in serious bodily injury or property damage. If
there are any questions concerning the use of Manuli ®
hoses, connectors, hose assemblies and hose protections
for a particular application, please contact Manuli Rubber
Industries.
PRODUCT INSTALLATION
The foregoing description of Manuli ® hoses, connectors,
hose assemblies, hose protections and the general
installation instructions are provided as information to
be considered when installing Manuli ® products. Proper
installation of hoses and connectors is essential to the
safe and proper operation of hose assemblies.
Additional factors which must be considered in achieving
a proper installation include correct minimum bend
radius to avoid hose collapse, possible abrasion of hoses
on rough surfaces or cutting edges, correct hose length
given the relation of potential movement between hose
ends, possible twisting or torsion of hoses in operation
or installation, and possible high temperature in areas
around the hoses.
Failure to consider all material factors with respect to
installation and improper installation of hoses, fittings
and hose assemblies can result in reducing the hose
assembly life or other failures that could result in serious
bodily injury or property damage.
HOSE INTEGRATION
117 by
WARNINGS
Manuli ® hoses and connectors are designed as integral
parts of hose assembly system to be used together and
they should only be used together or in conjunction with
other types of fittings for the Manuli ® hose recommended
by Manuli Rubber Industries and subsidiaries. Failure to
do so may result in reducing the hose assembly life or
other failures which can result in serious bodily injury or
property damage.
Product selection, product installation and hose integration
guide lines are essential to the proper operation and safe
use of the Manuli ® hoses, connectors, hose assemblies
and related equipment. Improper installation of the
hoses, connectors and hose assemblies can result in
serious injury or property damage.
Further information on selection, installation and
maintenance of hose and hose assemblies is described
in “SAE Recommended Practice J1273 2001”.
If you have any questions regarding the proper product
selection and hose installation, please contact the Manuli
Technical Center based in Italy.
Warning!
Failure or improper selection or improper use of any of
the products found on this Manuli catalogue or related
items can cause death, personal injury and/or property
damage. Before using any product, it is important that
you analyze all aspects of your application and review
the information explained in the current catalogue.

or exempting or indemnity terms contained herein, such objections must be
brought to the attention of Fluiconnecto, in writing, before conclusion of any such

Manuli Fluiconnecto agrees to the deletion or modification of any such
term, appropriate increases in the price of Products to be supplied under such
agreement may be agreed to reflect any increase in risks and obligations which
Manuli Fluiconnecto may thus agree or bear.
