SEALS - WHERE LEAKAGE CHALLENGES MEET INNOVATIVE SOLUTIONS
WHATEVER THE SEALING REQUIREMENT, XERKIN WILL HAVE A SOLUTION

Quad Rings/X Rings

The sealing principle of X-rings / quad rings largely corresponds to that of O-rings, but they have a double sealing action and are thus also called four-lobed seals. X-rings automatically act as double sealing elements:

  • Diametral compression in a rectangular groove
  • Sealing through system pressure
  • Acts in both directions

Advantages: X-rings vs. O-rings

  • Lower diametral compression force required, resulting in less wear due to reduced friction
  • Better sealing performance through four sealing lips, which at the same time form a lubricant channel
  • Higher stability in dynamic applications, no twisting in the groove, less torsion

 

  1. ​O-Rings are a simple but very versatile sealing solution.
  2. Used predominantly in static applications but can be used in certain dynamic applications.
  3. Can be combined with a backup ring to increase the pressure tolerance and assist in resisting extrusion.
  4. Available in a wide variety of materials in a wide variety of sizes.
  5. Nitrile 70A Duro- Precision Moulded.
  6. Used in a wide variety of applications that simple yet effective solutions.
  7. Recommended for static applications only.
  8. Hydraulic fluids, petroleum fuels and oils​.
