Premium piston seals with integrated metal for extreme-duty hydraulic/pneumatic cylinders. Engineered for TDUOP/PDEP/PDP configurations, our bonded design combines NBR/PU sealing elements with stainless steel inserts to eliminate extrusion under 5000+ PSI pressure and 1+ m/s sliding speeds.
Key Specifications
Structure: Metalfully encapsulated in rubber/urethane
Materials: NBR (Standard) / PU (Abrasion Resistance) / FKM (High-Temp)
Pressure: 400 bar dynamic | 600 bar static
Temperature: -30°C to +110°C (NBR) | -40°C to +200°C (FKM)
Surface Speed: ≤1.5 m/s
Standards: ISO 7425-1, DIN 3770
Core Advantages
Zero Leakage: Dual-lip design maintains seal integrity after 1M+ cycles
Anti-Extrusion: Metalprevents material creep in high-pressure side loads
Reduced Friction: Optimized lip geometry cuts breakaway force by 40%
Easy Installation: Pre-notched grooves for snap-fit assembly
Industrial Applications
Hydraulic presses & injection molding machines
Construction equipment cylinders (excavators, loaders)
Pneumatic actuators in automation systems
Marine hydraulic rams
Mining cylinder rebuilds
Agricultural machinery
Customization Options
