3. Pressure vs. Temperature Relationship
| Temperature | 20°C | 50°C | 100°C | 150°C | 200°C |
|---|---|---|---|---|---|
| Pressure Ratio | 100% | 50% | 35% | 30% | 10% |
| Max Working Pressure (Reference) | 17bar / 15bar / 10bar 8bar / 7bar |
9bar / 8bar 5bar / 4bar |
6bar / 5bar / 4bar 3bar / 2bar |
5bar / 3bar 2bar |
2bar / 1bar |
Warning: Burst Pressure is approximately 3 times the Max Working Pressure. Pressure resistance decreases significantly as environmental and fluid temperatures increase.
