Installation

Benefits

High pressure capability and wide temperature range

Excellent fluid compatibility including water-based fluids (H-PU)

Exceptional abrasion resistance

Highly extrusion resistant

Available in diameters up to 2100 mm

Applications

The 206 Symmetrical Piston Series U-cup, due to its versatility as both a piston and rod seal, can be used in a wide variety of applications. Recommended where dynamic sealing action is required simultaneously on the inside and outside diameters. Examples are often encountered in specialty sensors, bolt tension equipment and hollow cylinders.

Typical applications include:

  • Mobile Hydraulics
  • Hydraulic Cylinder Rebuild
  • Agricultural Hydraulics
  • Construction Equipment
  • Hydraulic Presses
  • Injection Molding Machines

The 206 Series Symmetrical Piston U-cup seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter, MP50  and MN01 injection-molded TPU. To suit a variety of applications, the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM.
