1. General information
1.1 Introduction
• These instructions apply to series 3T barb connectors,
also referred to below as connectors.
• Read the instructions completely before using our
products to prevent injuries, material damage and
malfunctions!
• Save the instructions for later reference.
• All rights including copyright and industrial property
rights are explicitly reserved.
1.2 Warnings
• Warnings are always identifi ed by a signal word. The
following signal words or hazard levels are used:
Danger: Failure to follow instructions will
lead to serious injuries or death. High risk le-
vel of endangerment.
Warning: Failure to follow instructions may
lead to serious injuries or death. Moderate
risk level of endangerment.
Caution: May lead to slight or moderate inju-
ries. Low risk level of endangerment.
Note: Refers to an instruction that must ab-
solutely be followed.
Information: Gives useful tips and recom-
mendations..
1.3 Special Hazards
• It must be ensured that the connector is resistant for
the media and temperatures that will be used. The re-
sistance of the connector with aggressive media de-
pends in individual cases on many variables (such as
the temperature, concentration ratio of the medium,
material, environment, tube material etc.). The person
ordering the connector is responsible for checking for
the specifi c application. In case of doubt install the con-
nector on a trial basis.
• Always comply with the safety data sheets or the safety
requirements for the media you are using!
• Before removing the connector it must be ensured that
there is no more medium in the fl exible tube system
and the pressure has completely dissipated. Exercise
caution for toxic, corrosive or hot media residue fl owing
out of the line or remaining in dead spaces.
1.4 General Safety Instructions
• The connector must be properly connected to the
fl exible tube system.
• Before installing the connector make certain that
external mechanical eff ects such as thrust and bending
forces are not acting on the fl exible tube system.
• Installation, commissioning, operation, installation,
maintenance, troubleshooting and disassembly must
only be performed by qualifi ed specialists with due con-
sideration of accident prevention regulations. Person-
nel must be capable based on their technical training
and experience of performing assembly tasks, follo-
wing technical specifi cations and recognizing possible
dangers.
• Personnel with defi cient knowledge must be trained
and instructed.
• Areas of responsibility and responsibilities must be pre-
cisely regulated and personnel must be monitored.
These safety instructions do not take into consideration
any:
• Coincidences and events that could occur at the cus-
tomer location during assembly, operation and mainte-
nance.
• Local safety requirements, for which the operating
company is responsible to ensure compliance, inclu-
ding assembly personnel who are used.
1.5 Designated Use
• The connector must only be operated within the permit-
ted usage ranges for pressure and temperature.
• Only the operating media named in the documentation
are permitted to fl ow through the connector.
• The connector must only be operated if it is in fl awless
technical condition.
• The connector must not be operated if it is in partially
assembled condition.
• If other operating modes are not named in the docu-
mentation, they must be approved with the manufac-
turer.
1.6 Reasonably Foreseeable Misuse
• Any usage other than designated use.
• Do not make any modifi cations to the product by your-
self!
• Components should only be retrofi tted after consulta-
tion with the manufacturer.

2 Manufacturer’s Specifi cation
2.1 Description
• The fl exible tube is pushed onto the barb by hand and
the tube expands. If the connection is to be secured
against shear, torsional or longitudinal forces, the tube
must be fi xed to the barb, e.g. with a pipe clamp.
2.2 Transport and Storage
• The connector must be protected against mechanical
damage, moisture, dirt and dust. The storage tempera-
ture range is 10 – 40°C.
• Avoid UV radiation and direct sunlight.
• Leave the connector in its original packaging to ensure
the best possible protection.
• Dispose of the packaging material according to dispo-
sal requirements/environmental protection regulations.
3 Technical Data
3.1 Dimensions
The exact dimensions of the connector can be found on
our homepage under the following link:
www.em-technik.com
Special sizes can be asked via [email protected]
3.2 Operating Medium
• Gaseous and liquid media that do not negatively aff ect
the physical and chemical properties of the relevant
housing and sealing material.
• If you have questions about resistance please contact
emtechnik.
• For the maximum permitted operating pressure/tempe-
rature see the pressure guide.
3.3 Pressure Guide
As the temperature rises, the eff ectiveness of the con-
nector falls, as shown by this table.

4 Assembly and Operation
4.1 Assembly Instructions
• Make certain the connector is suitable for the relevant
application. The connector must be suitable for the
operating conditions of the linesystem (medium, con-
centration, temperature and pressure) as well as the
relevant ambient conditions.
• Check the connector for transport damage before in-
stalling it. If the connector is damaged do not install it.
• The planner, the construction company or operating
company are responsible for the positioning and ins-
tallation of the connector. Planning and installation er-
rors can adversely aff ect the reliable functionality of the
connector and may represent a signifi cant potential for
hazard.
• After the connector is installed perform a tightness and
function check.

4.2 Tools Required
The tools required for installation and assembly are not
included with delivery.
4.3 Connect Thread Side
• The connector must be connected so it is free of
mechanical stress.
• The connector can have a male or female thread (ISO,
DIN, ANSI) and can be connected with various connec-
ting elements of the emtechnik system.
Cylindrical thread Conical thread
Sealing is provided by a sealing collar for
Cylindrical threads (G, M or UNF).
A version with an O-ring is also possible.
Sealing is provided
by the thread itself
for Conical threads
(NPT).
Sealing Collar O-Ring Thread
• Each thread must always be connected with the same
thread type.
• If a plastic connector is used in combination with a me-
tallic male fi tting, additional sealing with Tefl on® tape is
recommended.

4.5 Connect Tube Side
• Push the fl exible tube onto the barb by hand. This wi-
dens the tube and locks and holds it in place. In additi-
on, the tube can be secured against slipping by means
of a pipe clamp.
4.6 Fastening Options
For the connectors are no fastening options intended.
5 Precondition for Commissioning
• Protect against leaks: Take protective measures
against exceeding the maximum permitted pressure
due to possible pressure surges.
• Check the tightness and function of the connector.
• In new systems and after repairs, fl ush the line system
to remove foreign materials.
6 Maintenance
• When used as designated, the connector is practically
wear-free and generally requires no maintenance.
• The operating company must perform regular visual in-
spections of the connector according to the operating
conditions to prevent leaks and damage.
7 Disposal
• When disposing of the connector and packaging,
comply with the relevant disposal requirements and
environmental protection regulations.
• When disposing of connector, pay careful attention to
any residues of toxic or corrosive media.
8 Return Delivery
Do not return before consulting with emtechnik.
1. Please consult with emtechnik.
2. Empty the connector properly.
3. Rinse and clean the connector thoroughly, especially
if the media is being conveyed are harmful, explosive,
hot, or hazardous in some other way.
4. For connectors that have been operated with aggres-
sive, corrosive, combustible, toxic or water polluting
media, a completely fi lled in clearance certifi cate must
always be included.
