Rod Seals

448 (dynamic glide ring, single acting for tandem operation)

glide ring section is rectangular and is provided with a stepped sealing edge on the pressure side. On the opposite side, the profile travels under a flat wedge/angle.

The profile geometry, when exposed to pressure, will tilt, yielding a high-pressure sealing point.



  • Very good static and dynamic sealing effect
  • Very good resistance to extrusion
  • No stick-slip effect
  • Compact design


Limitations on use:

  • Operation pressure: Up to 40 MPa (400 bar)
  • Velocity Reciprocating: to 15 m/s
  • Temperature: -40°C to 200°C
