Silicone Rubber X-Rings

As a leading manufacturer in China, Aobo Silicone provides complete sealing solutions covering hydraulic, pneumatic, vacuum, and high-pressure piping systems. Our Silicone Rubber X-Rings are designed with industrial applications in mind, balancing sealing reliability, durability, and ease of installation to ensure stable performance under demanding conditions. Whether used in hydraulic cylinders, pumps, valves, or automated pneumatic equipment, the X-Rings effectively prevent leakage, reduce maintenance, and improve system efficiency. Every product is rigorously tested before shipment to ensure consistent performance, offering long-term reliability for your equipment.

Core Advantages

Silicone Rubber X-Rings adopt a standard X-shaped cross-section and function as self-energized, double-acting seals. They rely on contact stress at the sealing interface to achieve sealing performance. Pre-compression during installation provides initial sealing, and as system pressure rises, the seal strengthens while distributing stress uniformly in multiple directions.

Key advantages include:

● Bidirectional Sealing: Four-lip design ensures sealing in both directions with uniform pressure distribution, preventing leakage without additional reverse seals.

● Low Friction and Wear Resistance: Optimized contact structure with built-in lubrication cavities reduces running friction, maintains wear resistance over long-term use, and extends service life.

● Wide Pressure Adaptability: Can withstand vacuum to 40MPa pressure without additional retaining rings, achieving self-adjusting sealing performance.

● Anti-Twisting and Easy Installation: Parting lines are away from the sealing surface to prevent spiral twisting. Compatible with standard O-ring grooves for convenient assembly and disassembly.

Silicone Rubber X-Rings combine standard X-shaped structure, durability, low friction, and adaptability to diverse operating conditions, providing reliable, long-term sealing performance while reducing maintenance costs and enhancing operational efficiency.

Product's application

These X-shaped sealing rings are widely used in many areas. To ensure they adapt to specific application scenarios, the following detailed usage situations are summarized:

Material selection recommendations

Usage Instructions

1. Ensure grooves are clean and free of burrs or sharp edges to avoid damaging the seal surface during installation.

2. Avoid prolonged exposure to strong acids, bases, or organic solvents to maintain material performance.

3. Perform a low-pressure test before system start-up to verify sealing, then gradually increase pressure.

4. Regularly inspect for wear or aging; replace immediately if cracks or abnormalities are detected.

5. Avoid continuous over-temperature operation to prevent premature material aging.

6. Store in a dry, shaded environment to protect seals during long-term storage.
