Standard Metric O-Ring Size
Dimensions
| Inside Diameter | 20.00 mm |
| Cross Section | 1.80 mm |
| Tolerance Class | N |
Compression Rate Guidance
- Static seals: 15-25% compression is ideal for most applications.
- Dynamic seals: 10-20% compression to reduce friction and wear.
- Groove width should typically be 1.1 to 1.3 times the O-ring cross section.
