Monthly – detailed inspection, clean sealing surfaces, check electrical continuity. Annually – replace O-rings, full inspection, re-lubricate. Store in cool, dry place with protective caps. Keep spare O-rings on hand. Proper maintenance extends connector life 3-5x. We provide maintenance kits with O-rings, grease, and tools.<\/p>\n<\/div>\n

After Every Use (5 minutes)<\/h3>\n

Step 1: Rinse Thoroughly<\/h4>\n
    \n
  • Use fresh water (low pressure spray)<\/li>\n
  • Rinse for at least 30 seconds<\/li>\n
  • Pay attention to threads and mating surfaces<\/li>\n
  • Ensure all salt\/debris removed<\/li>\n<\/ul>\n

    Step 2: Dry Completely<\/h4>\n
      \n
    • Use compressed air or lint-free cloth<\/li>\n
    • Ensure no moisture in crevices<\/li>\n
    • Air dry in clean environment<\/li>\n

      Step 3: Visual Inspection<\/h4>\n
        \n
      • Check for obvious damage (cracks, dents)<\/li>\n
      • Inspect O-ring for cuts or debris<\/li>\n
      • Verify protective caps are in place<\/li>\n
      • Note any concerns for follow-up<\/li>\n<\/ul>\n

        Step 4: Apply Protective Lubricant<\/h4>\n
          \n
        • Apply thin film of dielectric grease to threads<\/li>\n
        • Light coating on O-ring (silicone grease)<\/li>\n
        • Don’t over-apply (attracts debris)<\/li>\n<\/ul>\n

          Weekly Maintenance (15 minutes)<\/h3>\n

              Thread Inspection<\/h4>\n
                \n
              1. Check threads for damage or wear<\/li>\n
              2. Clean with soft brush<\/li>\n
              3. Apply fresh anti-seize compound<\/li>\n<\/ol>\n
