EO2-Plus
Tube end
Leak free connection requirements
• Leak free in extreme long term use
• No welding, brazing, flanging
• Safe assembly by elimination of potential
assembly errors
• Reducing individual parts
• Reducing assembly costs

Advantages of soft sealing
• Avoids infiltration of dirt, scratches and air
• More tolerant when under-assembled
• Flexible to high vibration and pressure impulses
• Pressure supported sealing effect:
the higher the pressure the better the sealing
effect

Features EO2-Plus
• Sealing and retaining rings are combined and
integrated in the nut so that they cannot fall out
• The individual components cannot be forgotten,
confused or assembled in the wrong orientation
• Reduced number of individual parts
• Fixed elastomeric sealing
• Pressure supported sealing effect
Assembly “to block“
Stop
Clear assembly check
Connection functions, when the gap
is closed:
Cutting
Spring effect
Tube-clamping
Elastomeric sealing
No “stress“ in 24° cone while assembling
Integrated pre-assembly tool
e.g. VOMO16SX
DOZ….. Works in the functional nut like a
pre-assembly tool
Sealing replaceable
Assembly advantages EO2-plus
• Highest assembly safety: clear assembly stop;
assembly torque increase
• Uniform and reliable fitting assemblies
• No re-tightening necessary
• Effective bite depth stop
• Several repeated assemblies
• Direct assembly possible with integrated assemblytool
