What is an X-Ring?

An X-ring, also known as a quad-ring or a four-lobed ring, is a specialized type of rubber sealing ring with a unique cross-sectional design. Unlike traditional O-rings, X-rings have two sealing surfaces, resulting in improved sealing performance and reduced friction. This innovative design offers superior sealing capabilities, making X-rings the preferred choice for various applications where leakage prevention is critical.


Enhanced Sealing Performance

X-rings provide a more effective seal due to their four-lobed design. This design ensures better contact.

Enhanced Sealing Performance

The reduced contact area of X-rings compared to O-rings results in lower friction, leading to less wear and longer component life. This makes X-rings ideal for dynamic sealing applications.with the mating surfaces, reducing the risk of leakage.

Reduced Friction

The reduced contact area of X-rings compared to O-rings results in lower friction, leading to less wear and longer component life. This makes X-rings ideal for dynamic sealing applications.

Resistance to Extrusion

X-rings are less prone to extrusion under high pressures, ensuring their integrity in demanding environments.


X-rings are versatile and can be used in a wide range of industries, including automotive, aerospace, hydraulic systems, and more. They excel in applications where temperature and pressure variations are common.


X-rings find applications in various industries, such as hydraulic systems, automotive engines, pumps, and rotary equipment.

They are indispensable in situations where precision sealing is essential, and reliability is paramount. Whether it's sealing hydraulic cylinders, preventing leaks in aircraft systems, or enhancing the performance of automotive engines, X-rings are a dependable choice.

At Siliconiton, we understand the significance of X-rings in rubber molded parts. Our commitment to innovation and quality ensures that we incorporate these advanced sealing solutions into our products.

When you choose Siliconiton, you're choosing reliability, precision, and the best-in-class X-rings for your rubber molded parts.
