Heavy Duty Three-Piece Rod Seal

Series 132: Heavy Duty Three-Piece Rod Seal

The 132 series is a robust three-piece rod seal that consists of a profiled H-NBR seal ring and two active anti-extrusion backup rings. It is designed for double-acting cylinders in heavy-duty applications subject to severe pressure spikes couples with high running clearance.



Long service life under the harshest conditions

Compatible with water-based fluids (H-PU)

Optimized for high running clearance

Easy installation


The 132 series, three-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
  • Injection Molding Machines

The 132 series rod seal features a robust profiled seal ring available in abrasion resistant H-NBR and two backup rings in high-strength thermoplastic. Standard materials are MP30, MN34, and MN31 available up to 3000 mm in diameter.
