Hydraulic piston rings are used in a variety of hydraulic applications:

  • Cylinders on road graders
  • Back hoes
  • Garbage trucks for compression or lifting
  • Fork trucks


  • Performs better than elastomer compounds in high and low temperatures.
  • Superior sealing performance with interlocking joint design.
  • Total fluid compatibility.
  • Double-acting seal designed to pass open ports.
  • Because the Permaseal® joint design is bi-directional, fewer rings are required in double-acting applications, and costly assembly errors are eliminated in all hydraulic cylinder applications.

We make a living by what we get, but we make a life by what we give.
