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.
