X-Rings (Quad Rings)

X-Rings, also known as Quad Rings, are four-lobed sealing rings designed to improve sealing stability compared to traditional O-Rings. Their unique geometry provides enhanced sealing performance in both static and dynamic applications while reducing friction and rolling.

Our X-Rings (Quad Rings) are manufactured for industrial sealing systems where improved sealing reliability, longer service life, and better groove stability are required.


What Are X-Rings (Quad Rings)?

X-Rings, commonly referred to as Quad Rings, are elastomer sealing elements with a four-lobed cross-section. Compared to standard O-Rings, X-Rings provide multiple sealing lines, resulting in improved sealing efficiency and reduced risk of spiral twist in dynamic applications.

From an engineering perspective, the quad-lobed profile helps distribute contact pressure more evenly, offering improved sealing performance at lower compression forces.


Sizes & Specifications

X-Rings are available in standard O-Ring size equivalents as well as custom dimensions for specific sealing grooves.

  • Equivalent sizes to AS568 O-Rings
  • Metric size options available
  • Standard and custom cross sections
  • Static and dynamic sealing designs

Proper groove design is essential to maximize the performance advantages of X-Rings in dynamic sealing systems.


Available Materials & Options

  • NBR (Buna-N) – Oil resistance, general industrial use
  • FKM (Viton® equivalent) – High temperature and chemical resistance
  • EPDM – Water, steam, and weather resistance
  • HNBR – Improved wear and mechanical strength
  • Silicone (VMQ) – Wide temperature range and flexibility
  • FFKM – Extreme chemical and temperature environments

Material selection depends on operating temperature, pressure, media compatibility, and motion type.


Hardness & Tolerances

  • Standard hardness: 70 Shore A
  • Optional hardness: 50, 75, 80, 90 Shore A
  • Industrial-grade dimensional tolerances
  • Precision tolerance available for critical sealing applications

Advantages Compared to O-Rings

  • Reduced rolling and twisting in dynamic applications
  • Lower friction due to reduced contact area
  • Multiple sealing lips for improved leak prevention
  • More stable positioning in the groove
  • Longer service life under dynamic conditions

Typical Applications

  • Hydraulic cylinders
  • Pneumatic actuators
  • Rotary sealing applications
  • Industrial pumps and valves
  • Automotive and industrial machinery

Custom & OEM X-Rings

We support custom and OEM manufacturing of X-Rings (Quad Rings) for industrial and equipment manufacturers. Custom dimensions, materials, and hardness options are available based on drawings or application requirements.

  • Custom sizes and profiles
  • Material formulation options
  • OEM and bulk production support
  • Drawing or sample-based development
