Quad© / X-Rings

X-rings, also known as Quad Rings©, are similar to O-rings, but have an x-shaped profile. When installed, X-rings seal with 4 contact surfaces, where standard O-rings seal with one larger single contact surface. This gives the X-ring twice the sealing surface of the standard O-ring. X-rings are most commonly used in reciprocating applications, where they provide reduced running and breakout friction, and reduce the risk of spiralling as compared to O-rings.

X-rings have the following benefits over standard O-rings:

  • Lower friction
  • Longer life
  • Less spiralling and twisting
  • Excellent sealing efficiency


Common Uses:

X-rings are used in a wide range of dynamic and static applications, including:

  • Reciprocating rods and plungers
  • Rotating and spiral movements on shafts and spindles
  • Radial-static seal for bushings, pipes, etc.
  • Axial-static seal for flanges, etc.
