Installation

Benefits

Designed specifically for large clearance applications

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 135 Series U-cup seal is typically used in high-clearance applications as a primary seal and functions well in moderate to high pressures. It is a popular choice to replace V-packing sets.

Typical Applications

  • Steel and aluminum processing
  • Mining
  • Agriculture
  • Construction equipment
  • Presses
  • Injection molding machines

 

The 135 Series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter. To suit a variety of applications the series is also available in NBR, H-NBR, EPDM and high temperature-resistant FPM. The backup ring materials include POM, PTFE with bronze filler and PEEK.
