Piston Seal U-Cup – Symmetrical – OR Loaded
Installation
Benefits
High pressure capability and wide temperature range
Excellent fluid compatibility including water-based fluids (H-PU)
Exceptional abrasion resistance
Available in diameters up to 2100 mm
Applications
The 207 Series Energized Symmetrical Piston U-Cup is ideal for applications requiring high sealing forces. This seal is available in a wide range of materials to cover applications where specialty fluids are present. Often used in conjunction with an anti-extrusion ring particularly when seal material has insufficient extrusion resistance. The seal is a symmetrical design allowing use as either for dynamic OD or ID sealing.
Typical applications include:
- Oil & Gas
- Mobile Hydraulics
- Hydraulic Cylinder Rebuild
- Agricultural Hydraulics
- Construction Equipment
- Hydraulic Presses
- Injection Molding Machines
The 207 Series Energized Symmetrical Piston U-Cup features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter, and MP50 injection-molded TPU. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
