UC90 Cast Polyurethane O-Rings – 90 Duro – Disogrin® 9251 TODI by Freudenberg

Designed for heavy-duty applications, The O-Ring Store LLC’s UC90 Cast Polyurethane O-Rings are crafted from high-performance Disogrin® 9251 material. Engineered to deliver superior wear resistance, outstanding strength, and unmatched durability, these O-Rings are the ultimate solution for high-pressure and high-temperature sealing challenges. Ideal for hydraulic systems, quick disconnects, and industrial machinery, these O-Rings provide reliability where others fail.

Key Features & Benefits

1. High-Performance Polyurethane Composition:
   • Made from 92A durometer TODI-cured “cast type” polyurethane for superior strength and flexibility.
   • Specifically developed for hydraulic applications requiring resilience and durability.
2. Exceptional Mechanical Properties:
   • Tensile Strength: 6,000 psi (41.4 MPa) for outstanding load-bearing capability.
   • Elongation: 400% for flexibility and deformation recovery under stress.
   • Compression Set: 26% after 70 hours at 158°F (70°C) for long-lasting sealing performance.
3. Temperature and Pressure Performance:
   • Temperature Range: -115°F to +250°F (-81°C to +121°C), with short-term peaks up to 300°F (149°C).
   • Pressure Rating: Handles up to 10,000 PSI without requiring back-up rings, even in high-pressure hydraulic systems.
4. Abrasion and Tear Resistance:
   • Outstanding resistance to wear, tear, and extrusion, even in highly abrasive environments.
   • Low compression set ensures maximum service life and reduced downtime.
5. No Back-Up Rings Required:
   • The superior strength of Disogrin® 9251 eliminates the need for back-up rings, even in extreme temperature and pressure conditions.
6. Versatile Applications:
   • Performs well in static, dynamic, and high-pressure sealing environments.
   • Low breakaway friction reduces energy use and improves efficiency.
