R\u00e9ponse rapide :<\/strong> Most leaks (80%+) are installation-related, not quality defects. Common causes: O-ring damaged\/pinched, insufficient torque, debris on sealing surface, O-ring not lubricated, cable not properly potted. Troubleshooting steps: 1) Inspect O-ring for damage, 2) Check sealing surfaces for debris, 3) Verify proper torque, 4) Check cable potting. If all correct and still leaking, contact us – may be warranty claim. We’ll help diagnose and resolve quickly.<\/p>\n<\/div>\n

Connector Leak Troubleshooting<\/h2>\n

Quick Diagnostic Flowchart<\/h3>\n

Step 1: When did leak start?<\/strong><\/p>\n

    \n
  • First use \u2192 Likely installation issue<\/li>\n
  • After many uses \u2192 Likely wear\/maintenance issue<\/li>\n
  • After impact\/damage \u2192 Likely physical damage<\/li>\n<\/ul>\n

    Step 2: Where is leak occurring?<\/strong><\/p>\n

      \n
    • At mating interface \u2192 O-ring issue<\/li>\n
    • At cable entry \u2192 Potting issue<\/li>\n
    • Through housing \u2192 Crack\/damage<\/li>\n<\/ul>\n

      Step 3: Visual inspection<\/strong><\/p>\n

        \n
      • O-ring visible damage? \u2192 Replace O-ring<\/li>\n
      • Debris on surfaces? \u2192 Clean thoroughly<\/li>\n
      • Housing cracked? \u2192 Replace connector<\/li>\n<\/ul>\n

        Most Common Leak Causes (80%+ of cases)<\/h3>\n

        1. O-Ring Issues (40% of leaks)<\/h4>\n

        Probl\u00e8mes :<\/strong><\/p>\n

          \n
        • O-ring pinched during assembly<\/li>\n
        • O-ring cut or nicked<\/li>\n
        • O-ring dried out\/hardened<\/li>\n
        • O-ring not seated in groove<\/li>\n
        • O-ring wrong size<\/li>\n<\/ul>\n

          Solutions:<\/strong><\/p>\n

            \n
          • Replace O-ring (use correct size)<\/li>\n
          • Lubricate with silicone grease<\/li>\n
          • Ensure proper seating in groove<\/li>\n
          • Don’t over-stretch during installation<\/li>\n<\/ul>\n

            2. Insufficient Torque (20% of leaks)<\/h4>\n

            Problem:<\/strong> Connector not tightened enough<\/p>\n

            Solution:<\/strong><\/p>\n

              \n
            • Hand-tight plus 1\/4 to 1\/2 turn<\/li>\n
            • Use torque wrench if specified<\/li>\n
            • Typical torque: 2-5 Nm (check specs)<\/li>\n
            • Don’t overtighten (can damage O-ring)<\/li>\n<\/ul>\n

              3. Debris on Sealing Surface (15% of leaks)<\/h4>\n
