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
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.
