Rod Seal – Double Acting – AE Ring



Long service life under the harshest conditions

Compatible with water-based fluids (H-PU)

Optimized for high running clearance

Easy installation



The 128 series, four-piece rod seal is ideal in heavy duty sealing applications where pressure spiking can occur.

Typical applications include:

  • Mining
  • Heavy duty clamp cylinders
  • Specialty high-pressure cylinders
  • Hydraulic rams
  • Various advancing and secondary cylinders

The 128 series rod seal features a robust NBR elastomer, a profiled seal ring in abrasion resistant polyurethane and two backup rings in high-strength thermoplastic.
