Symmetrical Compact Rod Seal

Series 114: Symmetrical Compact Rod Seal

The 114 series compact rod seal is one of System Seals’ most popular designs used in standard duty applications. Its symmetrical design ensures that the seal lip forces are equal for every cross section and diameter. The 114 is widely used in standard – to – moderate – duty hydraulic applications. Manufactured in a variety of materials and sizes from 6 mm up to 2100 mm in standard and custom diameters.




High pressure capability and wide temperature range

Excellent fluid compatibility including water-based fluids (HNBR)

Exceptional abrasion resitance

Available in diameters up to 2100 mm



The 114 series compact rod seal is one of the most versatile seals typically used as a primary seal in moderate-to-high pressure applications.

Typical applications include:

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

The 114 series rod seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter, and HNBR 85A. To suit a variety of applications, the 114 series is also available in NBR, H-NBR, EPDM, MP50 injection molded TPU and high temperature-resistant FPM.
