Product Specifications
| Material | Nitrile Rubber (NBR) |
|---|---|
| Hardness | 70-90 Shore A |
| Color | Black |
| Operating Temperature | -20°C to 140°C |
| Primary Function | Hole seal, oil sealing |
Key Advantages
- Excellent resistance to oil, water, solvents, and high-pressure hydraulic fluids
- Low permanent compression set for reliable long-term performance
- Superior abrasion resistance and elongation properties
- Ideal for hydraulic cylinder applications requiring durable sealing solutions
Application Considerations
Compatibility Limitations
- Not suitable for use with polar solvents including ketones, nitrohydrocarbons, MEK, and chloroform
- Limited weather resistance - requires protection from ozone and ultraviolet radiation damage
Primary Application Areas
- Hydraulic cylinders and systems
- Fuel tanks and lubricating oil reservoirs
- Petroleum system hydraulic oil applications
- Gasoline and silicone oil environments
Note: As core components in hydraulic systems, our NBR O-rings work alongside other sealing elements including dust rings, piston seal rings, and piston rod seal rings to ensure comprehensive system integrity.
