X Ring Overview
X Rings are versatile seals, fitting standard O Ring dimensions, serving both stationary and mobile sealing needs.
With a unique four-surface design, unlike the two surfaces of O Rings, X Rings create uniform contact pressure, reducing twisting, rolling, leaks, and early failures. Their distinctive four-lobed shape expands the sealing area, minimizing squeeze requirements for efficient seals and extending lifespan.
X Rings’ parting lines, set apart from the sealing surface, prevent leakage, surpassing issues tied to irregular O Ring parting lines.
Also known as Quad Rings or Nu-LIPs, X Rings excel in hydraulic systems, automotive engines, and industrial machinery, outperforming standard O Rings with their superior sealing capabilities.
Choosing X Ring Materials
Choosing a suitable X Ring material is crucial for performance and longevity. Consider fluid/gas compatibility, temperature range, pressure capacity, size, groove dimensions, and environmental conditions.
Common Materials:
- Nitrile Rubber (NBR): General-purpose, resists oil and fuel, suitable for automotive and industrial applications.
- Viton™: High-performance, excels in chemicals and high temperatures.
- Silicone: Non-toxic, high-temperature resistance, ideal for medical and food-grade use.
- EPDM: Weathering and UV resistance, suitable for outdoor applications.
Compatibility Check:
Ensure material compatibility with sealed fluid/gas to prevent swelling or degradation and is capable of withstanding operational temperatures.
Pressure Rating:
The material should endure pressure without failing or leaking.
Size and Groove Dimensions:
Proper fit and sealing depend on the correct dimensions.
Environmental Considerations:
Chemical exposure or abrasion requires materials with good resistance, while UV radiation or extreme temperatures demand weathering or high-temperature resistance.
Advantages of X Rings
- Superior sealing performance: X Rings have four sealing surfaces, ensuring a more uniform and effective seal compared to O Rings with two surfaces. This minimises the risk of leaks and premature failure.
- Enhanced resistance to twisting and rolling: X Rings remain stable during movement, which is crucial for high-pressure scenarios where movement-induced compromises can occur.
- Reduced extrusion risk: X Rings withstand extrusion caused by high-pressure situations, preventing seal material from being forced into component gaps.
- Lower friction and wear: X Rings generate less heat and experience reduced wear on mating surfaces. This leads to extended service life and lower maintenance costs.
- High-speed suitability: X Rings’ reduced friction and wear enable operation at higher rotational speeds, making them ideal for applications with such demands.
