How do I properly maintain underwater connectors?
Quick Answer: Simple maintenance routine: After each use – rinse with fresh water, dry, inspect O-rings. 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 […]
My connector is leaking. Is it a quality issue or installation problem?
Quick Answer: 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 […]

How do I match connectors to my existing cables?
Quick Answer: Cable matching is critical for reliable connections. Key factors: Cable outer diameter (must fit connector), number of conductors (must match connector pins), conductor size (must handle your current), jacket material (must suit your environment). We offer cable assembly service – send us your cable specs or samples and we’ll match the right connector. […]
Will this connector material work in my environment?
Quick Answer: Material selection depends on your water type and conditions. Quick guide: Freshwater = 304 or 316L stainless (both fine). Saltwater = 316L stainless minimum. Harsh saltwater (hot, polluted, high flow) = Duplex stainless or Titanium. Extreme depth/weight critical = Titanium. Avoid aluminum in saltwater (corrodes quickly). Tell us your environment and we’ll recommend […]
I’m not technical. How do I choose the right depth rating?
Quick Answer: Don’t worry—we’ll help you choose. Simple rule: Pick a connector rated for at least 1.5x your maximum operating depth. If your ROV goes to 100m, choose 150m+ rating (we’d recommend 300m for safety margin). Most common ratings: 50m (pools/shallow), 100m (coastal), 300m (inspection ROV), 500m (offshore), 1000m+ (deep water). Tell us your application […]
