What lubricant should I use on underwater connectors?
Quick Answer Use silicone-based grease (Dow Corning 111 or equivalent) for O-rings. Never use petroleum-based products. Apply thin, even coat to O-rings only – not on electrical contacts. Reapply after each mating. Quick Answer Use silicone-based grease (Dow Corning 111 or equivalent) for O-rings. Never use petroleum-based products.

How to prevent thread galling on titanium connectors?
Quick Answer Thread galling prevention: (1) Use anti-seize compound on threads, (2) Don’t overtighten, (3) Use proper torque wrench, (4) Clean threads before mating, (5) Replace damaged threads immediately. Titanium is prone to galling without proper lubrication. Quick Answer Thread galling prevention: (1) Use anti-seize compound on threads, (2) Don’t overtighten, (3) Use proper torque wrench, (4) Clean threads before mating, (5) Replace damaged threads immediately. Titanium is prone to galling without proper lubrication. What is Thread Galling? Galling is a form of wear where metal surfaces seize due to friction and pressure. Titanium is especially susceptible because: Protective oxide layer breaks down under friction Bare metal welds to itself […]
