Installation
Benefits
High-pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
Applications
The 163 series rod seal is typically used in heavy-duty applications, where pressure spike and large extrusion gaps exist.
Typical applications include:
- Mining
- Mobile Hydraulics
- Hydraulic Cylinder Rebuild
- Agricultural Hydraulics
- Construction Equipment
The 163 series rod seal features high-grade polyurethane. Standard materials are MP03 machined 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.
