Designed specifically for demanding hydraulic systems, ED Hydraulic Rubber Seals offer excellent sealing performance, wear resistance, and long service life.
Common Hydraulic System Challenges
Premature seal failure under high-pressure cycles causing oil leakage and increased maintenance costs
Pressure drop due to seal wear affecting actuator output accuracy and stability
Need for reliable sealing solutions compatible with complex hydraulic media (mineral oil, HFA/HFB, water-glycol)
The ED-type seal ring provides professional solutions to these challenges. As a classic dynamic seal for piston rods and pistons, it offers dual-seal protection under high-pressure and high-frequency conditions, making it ideal for hydraulic cylinders, construction machinery, injection molding machines, and industrial power systems.
Core Product Advantages
Dual Sealing Reliability: O-rings provide initial preload while the ED main sealing lip ensures high-pressure dynamic sealing
Superior Extrusion Resistance: Robust retainer design prevents sealing lip extrusion into gaps under extreme pressure
Exceptional Wear Resistance: High-quality rubber formulation with optimized lip design reduces wear on mating parts
Broad Media Compatibility: Custom rubber materials available for various hydraulic fluids including mineral oils and biodegradable oils
Shipbuilding and Offshore Engineering: Deck machinery, rudder hydraulic systems
Installation and Maintenance Guide
Pre-installation Notes
Check groove dimensions to ensure they are clean and free of burrs
Apply clean hydraulic oil to the sealing lip and O-rings
Use dedicated installation tools to avoid scratching sealing surfaces with sharp tools
Ensure sealing direction is correct (main sealing lip faces the high-pressure side)
Maintenance Recommendations
Regularly check system oil cleanliness as contamination is a primary cause of seal failure
When replacing seals, inspect piston rod/cylinder barrel surfaces for scratches or corrosion
