Rod Seal U-Cup – Symmetrical – OR Loaded – AE Ring



Symmetrical design for optimal sealing performance

Internal O-Ring works more efficiently at varying pressures

Double-lip design increases efficiency and performance

Highly extrusion resistant in large gap conditions

Easy to install


The 133 Series rod seal is typically used in heavy-duty applications, where pressure spikes and large extrusion gaps exist.

Typical applications include:

  • Mining
  • Mobile Hydraulics
  • Hydraulic Cylinder Rebuild
  • Agricultural Hydraulics
  • Construction Equipment

The 133 Series rod seal features high-grade polyurethane. Standard materials are MP03 H-PU, NBR O-ring and polyacetal backup ring. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
