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

Sealing function EO2-Plus

• 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
