Problem this solves
Use this comparison to choose NBR or Viton based on temperature, media, and budget.
NBR vs Viton comparison
| Factor | NBR | Viton (FKM) |
|---|---|---|
| Temperature | Moderate | High |
| Cost | Lower | Higher |
| Chemical resistance | Good for oils | Better for fuels/solvents |
| Compression set | Standard | Improved |
| Typical use | General purpose | High temp, aggressive media |
Material selection steps
- 1Identify media, temperature, and pressure.
- 2Confirm exposure to fuels or solvents.
- 3Choose hardness based on sealing load.
- 4Verify gland dimensions and squeeze.
- 5Request a sample if application is critical.
Include When Confirming Specifications
- O-ring dimensions (ID/OD/cross-section)
- Media and temperature range
- Material preference (NBR/Viton)
- Hardness and color if required
