Supplier's note

  1. Technical Breakthroughs:

    • Material Blends: NBR/EPDM composites provide 20% better oil resistance than standard nitrile seals.
    • Precision Manufacturing: CNC-machined square sections ensure a 30% tighter seal compared to molded alternatives.
    • Certifications: RoHS compliance eliminates lead-based additives, reducing environmental impact by 40%.

  2. Version Selection Guidance:

    • Base Model: Ideal for general industrial use (e.g., HVAC systems) where moderate temperature and chemical exposure are standard.
    • Advanced Model: Suitable for automotive or food processing equipment requiring enhanced oil resistance and durability.
    • Pro Model: Designed for extreme environments (e.g., chemical plants, aerospace) where triple-certified chemical resistance and ultra-precision are critical. With the Pro’s EPDM blend and -30°C to +150°C range, you can safely seal high-pressure reactors or cryogenic systems. Pair its ±0.05mm tolerance with stainless steel components for zero-leak performance.
