7 bars<br />
*The pressure indications also depend on the tubing material. For application with liquids or<br />
vacuums, please contact us.<br />
Under certain circumstances, depending on the used hoses, the connectors<br />
may also be used at higher pressures and temperatures. Please contact us.<br />
Applicable tube materials/types*<br />
Plastic tubes PE, PA, or PUR tube materials which correspond<br />
to the tolerances (see below). For soft and<br />
thin-walled tubes, we generally recommend the<br />
use of supporting collets as well as the control<br />
of pressure ranges of the tubes used. (Please<br />
contact us).<br />
Metal tubes (soft) Brass, copper-aluminium tubes which<br />
correspond to the tolerances (see below).<br />
Metal tube (hard) resp. Here is necessary to check the usability of the<br />
plug-in<br />
surface treated connectors first.<br />
Please contact us.<br />
It is absolutely required that the outer diameter of the tubes does not show<br />
any defects or longitudinal marks.<br />
Installation<br />
Check if all tubes and connectors are clean and undamaged before<br />
using them. It is imperatively necessary that the tube surface does not show<br />
any corrugations, dents or any similar damages.<br />
Tube tolerances<br />
Our connectors may be used with the following tube diameters and<br />
tolerances.<br />
Tube oD (mm) Ø 15 mm - 28 mm<br />
Tolerances (mm) +0.05/-0.10<br />
Installation and system test<br />
All tubes and connectors must be clean and intact before they may be used.<br />
After the installation, all hose and connector installation<br />
are to be tested pressure-resistant in order to guarantee that the system is<br />
pressure-tight before it is delivered to the customer.<br />
Also refer to: "How to create a connection".<br />
Testing the system<br />
For test purposes we recommend you to test the system before<br />
commissioning as follows, irrespective if it is concerning a new or an existing<br />
system:<br />
· The system has to be tested at an operating pressure of 10 bars during<br />
a period of 10 minutes.<br />
· Pressure relief of the system to 0 bar.<br />
· Then, the system is to be tested subsequently with a working pressure of<br />
2 bars over a period of time of 10 minutes.<br />
Built according to CE directives<br />
Chemical liquids<br />
When using chemical or other potentially<br />
aggressive liquids, please contact us.<br />
Attention: our connectors are not appropriate for the use with explosive<br />
gas, paraffin and other fuels.<br />
Protective caps<br />
They are available as an additional protection against slipping off of the<br />
hose or as a protection (marking) for colour distinction (see accessories on<br />
the following pages).<br />
Food resistance<br />
All connectors mapped in this catalogue fulfil the directives of the food<br />
regulation and may thus be used for food applications without any<br />
problems.<br />

Max. torque 4.0 Nm* 5.0 Nm* 7.0 Nm*<br />
* These values may vary. It is depending on the thread sealing material.<br />
It is recommended to test all installations before use,<br />
in order to guarantee that the assembly has been correctly performed. The<br />
tightness is also to be tested.<br />
The maximum torque is geared to the use of our connectors and refers to<br />
types used in this catalogue according to the international specification.<br />
warranty<br />
Although we give a warranty against manufacturing errors and material<br />
defects, it is the responsibility of the user to guarantee, that the<br />
connectors and similar products are appropriate for the application. The<br />
installation must be performed according to our recommendations and the<br />
valid releases and national standards have to be respected and followed.<br />
Within this period, no leakages are to be detected at the connections.<br />
Therefore, sealing plugs and end caps are sometimes useful in order to<br />
simply close the outflow openings and to create a sealed connection.<br />
When our products are integrated into complete systems, we recommend<br />
self-contained tests (functional checks, flow rate checks, chemical<br />
resistance, etc.). For safety checks, we further recommend to document<br />
these test results in writing.<br />
