Reference Table
| Application | Compression |
|---|---|
| Static seal | 15% – 25% |
| Dynamic seal | 10% – 20% |
Groove Design Recommendations
- Groove width = 1.1 to 1.3 × O-ring cross section
- Static seal surface finish: 16 – 32 μin Ra
- Dynamic seal surface finish: 8 – 16 μin Ra
- Maximum stretch during installation: ≤ 6%
- Lead-in chamfers: 15° – 20° to prevent cutting
