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.

Applications

• Heavy Equipment: Bulldozers, forklifts, agricultural machinery, and mobile lifts.
• Industrial Systems: Injection molding machines, valves, general cylinders, and flanges.
• Hydraulics and Pneumatics: Quick disconnects, high-pressure hydraulic systems, and water applications.
• Power Tools: Air tools, nail guns, riveting equipment, and high-end paintball markers.
• Construction and Manufacturing: Mobile arm trucks and high-pressure seals for static and dynamic applications.
