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 kits with O-rings, grease, and tools. Connector Maintenance Guide Maintenance Schedule Overview Frequency Tasks Time Required After Every Use Rinse, dry, visual inspection 5 minutes Weekly (if in regular use) Detailed inspection, clean contacts 15 minutes Monthly O-ring inspection, electrical test 30 minutes Annually (or 50-100 cycles) Replace O-rings, full service 1 hour After any […]
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 us – may be warranty claim. We’ll help diagnose and resolve quickly. Connector Leak Troubleshooting Quick Diagnostic Flowchart Step 1: When did leak start? First use → Likely installation issue After many uses → Likely wear/maintenance issue After impact/damage → Likely physical damage Step 2: Where is leak occurring? At mating interface → O-ring issue […]

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. Popular cable types: Polyurethane (flexible, ROV), TPE (general purpose), Polyethylene (deep water). Tell us your cable OD and we’ll recommend compatible connectors. Cable-Connector Matching Guide Key Matching Factors 1. Cable Outer Diameter (OD) Most critical dimension! Connector must grip cable properly. Cable OD Range Compatible Connector Series Gland Size 4-6mm MCM miniature series Small 6-10mm […]
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 the right material. 316L stainless works for 90% of marine applications and is our standard offering. Material Selection Guide Quick Material Selector Your Environment Minimum Material Recommended Premium Option Freshwater (lake, river) 304 Stainless 316L Stainless Titanium Brackish water (estuary) 316L Stainless 316L Stainless Duplex/Titanium Saltwater (ocean, standard) 316L Stainless 316L Stainless Titanium Hot saltwater […]
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 and we’ll recommend the right rating. All our connectors are tested beyond their rating for extra safety. Choosing Depth Rating – Simple Guide The Golden Rule Choose a connector rated for at least 1.5x your maximum depth. Why? This gives you: ✅ Safety margin for unexpected conditions ✅ Accounts for pressure spikes during deployment ✅ […]
