Quick Answer
Hand-tighten until snug, then use spanner wrench for final 1/8 to 1/4 turn. Typical torque: 2-5 Nm for small connectors, 5-15 Nm for large. Over-tightening damages O-rings and threads.
Mating Force Guidelines
| Connector Size | Hand Tighten | Final Torque | Max Torque |
|---|---|---|---|
| Miniature (≤20mm) | Snug | 2-3 Nm | 5 Nm |
| Standard (20-40mm) | Snug | 3-8 Nm | 10 Nm |
| Large (≥40mm) | Snug | 8-15 Nm | 20 Nm |
Proper Mating Technique
- Align connector halves (match keying)
- Hand-tighten until resistance felt
- Use spanner wrench for final 1/8-1/4 turn
- Do NOT exceed recommended torque
- Verify locking mechanism engaged
Signs of Over-Tightening
- ❌ O-ring extrusion visible
- ❌ Threads difficult to engage next time
- ❌ Housing deformation
- ❌ Connector stuck during unmating
