A: We specialize in perfluoroelastomer (FFKM) seals, spring energized seals (GreatSeal®), O-rings, high-speed rotary seals, food & pharmaceutical grade seals, oil & gas industry seals, as well as custom seals for compressors, hydraulic equipment and industrial machinery. We provide high-performance alternatives to imported sealing products.

A: Please offer the key working conditions: medium type, operating temperature, static/dynamic pressure, motion type (reciprocating, rotary or static) and running speed. Our technical team will recommend the most suitable material and seal model for you.

A: Spring energized seals perform excellently under extreme working conditions such as high temperature, high pressure, strong chemical corrosion, vacuum and ultra-low temperature. They are widely used in chemical, semiconductor, pharmaceutical, food processing, valve and hydraulic systems.

A: FFKM seals feature universal chemical resistance, wide temperature range and long service life. They can withstand temperatures up to 260°C, and are ideal for strict hygiene and highly corrosive environments in pharmaceutical, semiconductor and fine chemical industries.

A: Yes. Our FDA-grade silicone and elastomer seals prevent dirt accumulation, suitable for food processing and CIP (Clean-in-Place) systems. All products comply with food and pharmaceutical industry hygiene standards.

A:

• NBR: Cost-effective, good oil resistance for general applications.
• HNBR: Better heat resistance and anti-aging performance than NBR, suitable for high-temperature oil media.
• FKM: Outstanding heat and chemical resistance for harsh corrosive conditions.
• FFKM: Top-level universal chemical resistance for the most extreme working environments.
• Silicone: Excellent for food, medical and clean applications with wide temperature adaptability.

A:

• Temperature: -70°C ~ +260°C; Special models support -120°C ~ +260°C.
• Pressure: Max 45MPa for dynamic working, max 80MPa for static working.
• Speed: Up to 15m/s for reciprocating motion, up to 1m/s for rotary motion.
• Specific parameters refer to individual product datasheets.

A: Our products are compatible with nearly all fluids, chemicals and gases. Feel free to send us the details of your working medium, and we will confirm the material compatibility for free.

A:

• Keep seal grooves clean without burrs or impurities.
• Lubricate properly and avoid twisting or scratching the seal.
• Maintain reasonable compression rate (15% – 30%).
• Install back-up rings under high pressure to prevent extrusion damage.
• Use professional tools to avoid eccentric loading.

A: Common reasons include improper model/material selection, installation damage, excessive clearance or misalignment, medium corrosion, high temperature aging, and fatigue of the energizing spring.

A:

• Wear: Improve lubrication, filter particle contaminants or select wear-resistant materials.
• Abnormal noise: Check shaft concentricity and add lubricant.
• Hardening & cracking: The seal exceeds the rated temperature or medium range, please replace with matched materials.

A: Yes. We can customize non-standard sizes, special materials, colors and structures according to your drawings or samples. Custom sealing solutions are available for special equipment.

A: Absolutely. Our seals match the performance of international famous brands, with shorter lead time and competitive cost.

A: Standard products are in stock for fast delivery. For customized orders, lead time depends on specifications and production processes. We support small trial orders and bulk orders.

A: We offer free services including model selection, groove design, material compatibility test, seal failure analysis and on-site installation guidance.

A: Strict quality control is implemented throughout production. We can provide material certificates, performance test reports and relevant industry certifications.

A: For quality-related issues after delivery, please contact us with photos or videos, and we will handle it promptly. We maintain long-term cooperation and communication with all customers.
