Product Advantages
I. Outstanding Sealing Performance
-
Comprehensive Sealing Guarantee: X-Ring products, with their unique structure, can effectively seal liquids, gases, and other media. They maintain stability and prevent leakage even in high-pressure, high-temperature, and complex chemical environments, ensuring the reliable operation of equipment.
-
Strong Adaptability: Suitable for a wide range of working conditions and environments, from high-temperature and high-pressure oil sealing in automotive engines to the highly reliable hydraulic and fuel systems in aerospace equipment, and to the sealing needs of machinery and pipelines in industrial manufacturing, X-Ring products can meet diverse requirements.
II. High Reliability
-
Durability: Made from high-quality materials that have undergone strict selection and special treatment, X-Ring products possess excellent physical and chemical properties. They can withstand mechanical movement, temperature changes, and media erosion over long-term use, resisting aging and wear. This leads to a longer service life, reducing equipment failure and maintenance costs.
-
Stability: During equipment operation, X-Ring products maintain a stable sealing state, unaffected by vibrations or impacts. Even under harsh conditions such as high-load operation and frequent start-stop cycles, they continue to work reliably, ensuring continuous and stable equipment operation and efficient industrial production.
III. High Safety
-
Equipment Safety: In critical fields like automotive and aerospace, X-Ring products prevent the leakage of lubricants and fuels that could cause fires or explosions. In the battery packs of new energy vehicles, they block moisture and impurities to avoid short circuits and fires, ensuring the safe operation of equipment.
-
Personal Safety: In food processing and pharmaceutical industries, their resistance to food-grade and pharmaceutical media ensures product quality and safety, preventing harm from the leakage of harmful substances. In medical devices, good biocompatibility reduces medical accidents and safeguards patient safety.
Usage Precautions
1. Prohibited Media
Strictly avoid contact with:
-
Highly polar solvents: Acetone, Methyl Ethyl Ketone (MEK);
-
Ozone environments (may cause rubber cracking);
-
Chlorinated hydrocarbons (e.g., chloroform, dichloromethane);
-
Nitro hydrocarbons (e.g., nitromethane).
Reason: These media cause rubber swelling, hardening, or chemical degradation, leading to seal failure.
2. Compatible Media
Recommended for:
-
Fuels (gasoline, diesel), lubricating oils;
-
Hydraulic fluids, silicone oils;
-
Water (freshwater/seawater), greases;
-
Air, inert gases.
Note: Confirm material compatibility for long-term exposure (e.g., NBR/FKM/EPDM resistance differences).
3. Operational Limits
4. Installation & Maintenance
Critical Requirements:
- Groove tolerancing: Design per ISO 3601 standards; avoid over-tightening (compression) or looseness (extrusion risk);
- Surface finish: Ra ≤0.4μm (axial seals), Ra ≤0.2μm (radial seals);
- Cleanliness: Remove all metal debris/dust before installation;
- Lubrication: Dynamic sealing surfaces must be coated with compatible grease (e.g., silicone-based).
5. Failure Prevention
- Regular inspection: Shorten replacement cycles in ozone/chemical exposure environments;
- Contamination control: Install filtration in hydraulic systems (target cleanliness ISO 4406 16/14/11);
- Material upgrade:
- Fuel exposure → Prioritize FKM (Fluorocarbon Rubber);
- Wide-temperature use → Select HNBR (Hydrogenated Nitrile) or FFKM (Perfluoroelastomer).
