Underwater connector maintenance

See also the pertinent instrument guides for instructions on caring for your cables and connectors.

Inspection

Routinely check for corrosion and for signs of dirt or debris. The pins on the connector should be clean and shiny. Check all the connectors for signs of damage like cracks or broken pieces. Replace the connector if there is any damage.

Cleaning instructions

Remove any accumulated dirt, biofouling, sand, or mud on or inside the connector using a spray-type contact cleaner; for example, isopropyl alcohol. Clean the pins with isopropyl alcohol using a soft applicator like a Q-Tip.

After cleaning the connector, new lubricant must be applied again prior to mating.

Lubricating instructions

RBR recommends using the Specialty Silicone Compound included in all RBR support kits. Other acceptable lubricants are: Dow DC-4, Molykote 44 Medium, and Dow DC-111.

It is not advisable to use silicone spray from a can or WD-40 as these may contain solvents harmful to the connectors. Silicone spray may be used from a pump bottle provided it does not contain solvents harmful to rubber (alcohols, ethers, esters, glycols, or ketones).

Steps

1. Apply the silicone compound to all female connectors before every mating.  
   Ensure each connector hole is filled with approximately 30% lubricant.
   
   

   

   
   
   

2. Verify that all the sockets are completely sealed, and a transparent layer of the silicone compound is visible on the face of the connector.
   
   

   

   
   
   

3. After lubricating, mate the male and female connectors, ensuring the trapped air is released.
