Description
Premium ED Ring Seals for Leak-Free Hydraulic Tube Fittings
Professional-Grade High-Pressure Dynamic Sealing Solutions
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
  • Simplified Installation: Integrated structure design enables easy installation and reduces assembly errors

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
