UC70 Cast Polyurethane O-Rings – 70 Duro – Disogrin® 70 AU 6865 TODI by Freudenberg

Engineered for superior sealing performance, The O-Ring Store LLC’s UC70 Cast Polyurethane O-Rings deliver exceptional durability, flexibility, and resistance to wear. Made from high-performance Disogrin® 70 AU 6865 TODI material by Freudenberg, these 70-durometer O-Rings are designed for demanding hydraulic, pneumatic, and industrial applications where reliability and long service life are critical.

Key Features & Benefits

  1. Premium Material - Disogrin® 70 AU 6865 TODI:
    • 70 Shore A hardness offers excellent flexibility, resilience, and sealing under dynamic or static conditions.
    • TODI-cured polyurethane provides superior tensile strength, abrasion resistance, and resistance to extrusion.
    • Specifically developed for O-Rings, ensuring optimal performance in harsh environments.
  2. Temperature and Pressure Resilience:
    • Temperature Range: -40°F to +200°F (-40°C to +93°C) for versatile use in hot and cold environments.
    • Handles high pressures up to 7,500 PSI without requiring back-up rings, thanks to its excellent mechanical strength.
  3. Outstanding Physical Properties:
    • Tensile Strength: 5,500 psi (37.9 MPa) for exceptional load-bearing performance.
    • Elongation: 450% for flexibility and deformation recovery under stress.
    • Compression Set: 25% after 70 hours at 158°F (70°C) ensures long-lasting performance without permanent deformation.
  4. Exceptional Resistance to Environmental Factors:
    • Excellent resistance to oils, fuels, hydraulic fluids, and greases.
    • High abrasion, tear, and extrusion resistance for longer service life.
    • Resists ozone, UV, oxidation, and weathering, making it suitable for outdoor and rugged conditions.
  5. Versatile Applications:
    • Designed for high-pressure and high-wear environments without requiring back-up rings, reducing complexity and costs.

Applications

  • Hydraulics and Pneumatics: Quick disconnects, valves, pumps, and cylinders.
  • Heavy Equipment: Forklifts, mobile lifts, bulldozers, and agricultural machinery.
  • Industrial Sealing Systems: Static and dynamic seals in injection molding machines and hydraulic systems.
  • Power Tools and Air Systems: Nail guns, riveting tools, and high-pressure air systems.
  • Fluid Power Systems: General sealing in high-pressure oil and water applications.
  • Aerospace and Automotive: Components exposed to aggressive fluids and wear.
