Compression Ring

Compression Ring

  • Hook Ring
    Designed for applications that require passing counterbores and retaining ring grooves.
  • Step Ring
    Restricts oil flow by eliminating the straight path.
  • Inside cut
    Inside surface is cut to allow the ring to be inclined during operation. So that the ring working surface lower edge line contact with the cylinder wall to assist initial running-in.
  • Under Cut
    The lower edge of the working surface is cut. While being a pressure ring, it also performs as an oil control ring.
  • Copper plated
    Increases initial running-in of new rings with the cylinder wall.
  • Notch
    Enhances the close fit between piston ring and cylinder wall.
  • Both –side keystone
    The cross section is wedge-shaped from both sides. Excellent in preventing ring sticking.
  • Slip In
    Increases lubrication of oil between the ring and cylinder liner.
  • Copper plated
    Increases initial running-in of new rings with the cylinder wall.
