Torque varies by size/material. Typical: Small 1-2 Nm, Medium 3-5 Nm, Large 8-15 Nm. Follow manufacturer specs. Use calibrated torque wrench. Overtightening damages; undertightening leaks.
Detailed Explanation
Torque Specifications by Size
| Connector Size | Torque Range | Thread Size |
| —————- | ————– | ----- | |
|---|---|---|---|
| Mini (<20mm) | 0.5-1.5 Nm | M12-M16 | |
| Small (20-40mm) | 1-3 Nm | M20-M24 | |
| Medium (40-60mm) | 3-8 Nm | M30-M42 | |
| Large (60-100mm) | 8-20 Nm | M50-M80 | |
| Extra Large (>100mm) | 20-50 Nm | M100+ |
### Material Considerations
| Housing Material | Torque Adjustment |
| —————— | ——————- | |
|---|---|---|
| チタン | Standard torque | |
| Stainless Steel | Standard torque | |
| ブロンズ | Reduce 10% | |
| プラスチック/コンポジット | Reduce 20-30% |
### Torque Wrench Requirements
おすすめだ：
– Calibrated torque wrench
– Range matching connector size
– Accuracy: ±3% or better
– Annual calibration
Consequences of Incorrect Torque
Overtightening:
– O-ring extrusion/damage
– Thread damage
– Housing cracks
– Difficult unmating
Undertightening:
– Water ingress
– Pressure failure
– Connector separation
– Electrical failures
Torque Procedure
- Clean threads
- Lightly lubricate (if specified)
- Hand-tighten first
- Apply torque in smooth motion
- Do not exceed specified torque
- Mark/torque seal for verification
