How Tight Should I Tighten the Connector? Is There a Torque Specification?

Hurtigt svar

Yes! HYSF connectors have specific torque values. Standard series: 2-3 Nm, Heavy duty: 5-8 Nm, Micro: 1-1.5 Nm. Over-tightening damages seals, under-tightening causes leaks.

Torque Specifications by Series

Why Torque Matters

Under-Tightening Risks

• ❌ Incomplete seal compression
• ❌ Water ingress at depth
• ❌ Connector loosening under vibration

Over-Tightening Risks

• ❌ O-ring extrusion and damage
• ❌ Thread stripping or galling
• ❌ Housing deformation

Torquing Procedure

1. Clean threads and inspect O-ring
2. Apply light silicone grease on O-ring only
3. Hand-tighten until O-ring contacts
4. Use torque wrench to apply specified torque smoothly
5. Mark connection with paint pen for future checks
