Product advantages:
‌
1. Superior Material Performance‌
  • ‌Wear & Pressure Resistance‌: F-PTFE composite combined with elastomer withstands ≤50 MPa pressure and extreme temperatures (-30°C to +100°C), ensuring zero leakage under prolonged use.
  • ‌Chemical Compatibility‌: Excellent resistance to swelling and aging caused by hydraulic oils, lubricants, and other media, preventing seal failure.

  • ‌2. Innovative Structural Design‌

  • ‌Low Friction & Anti-Extrusion‌: Unique open-profile design maintains low friction coefficients even under high pressure or large clearance conditions, reducing equipment "low-pressure creep."
  • ‌Easy Installation‌: Tool-free installation for monoblock pistons, compatible with ISO-standard grooves to minimize maintenance costs.

  • ‌3. Versatile Application Scenarios‌

  • ‌Extreme Conditions‌: Ideal for 24/7 mining operations, high-impact hydraulic cylinder systems, excavator and hammer improving heavy equipment lifespan by over 30%.
  • ‌Cross-Industry Use‌: Widely applied in Excavators, Agricultural Machinery,Crusher , and more, meeting diverse needs like sealing, noise reduction, and insulation.

  • ‌4. Certification & Service Assurance‌

  • ‌Global Certifications‌: ISO-certified manufacturing standards, compatible with leading brands (e.g., CAT, Parker) in global supply chains.
  • ‌Rapid Support‌: Emergency repair parts, technical guidance, and global inventory (e.g., direct shipping from China, US stock) to reduce downtime.
