SubConn® handling instructions

 Follow these instructions carefully to ensure the correct use of your SubConn® connectors.

Handling

  • Always apply grease before mating
  • Disconnect by pulling straight, not at an angle
  • Do not pull on the cable and avoid sharp bends at cable entry
  • When using a bulkhead connector, ensure that there are no angular loads
  • Make sure to apply the recommended torque when tightening bulkhead nuts (see page 117)
  • SubConn® connectors should not be exposed to extended periods of heat or direct sunlight. If a connector becomes very dry, it should be soaked in fresh water before use

 

Greasing products

 

Greasing and mating above water (dry mate)

  • Connectors must be greased with Molykote 44 Medium before every mating
  • A layer of grease corresponding to minimum 1/10 of socket depth should be applied to the female connector
  • The inner edge of all sockets should be completely covered, and a thin transparent layer of grease left visible on the face of the connector
  • After greasing, fully mate the male and female connector in order to secure optimal distribution of grease on pins and in sockets
  • To confirm that grease has been sufficiently applied, de-mate and check for grease on every male pin. Then re-mate the connector

 

Greasing and mating under water (wet mate)

  • Connectors must be greased with Molykote 44 Medium before every mating
  • A layer of grease corresponding to approximately 1/3 of socket depth should be applied to the female connector
  • All sockets should be completely sealed, and a transparent layer of grease left visible on the face of the connector
  • After greasing, fully mate the male and female connector and remove any excess grease from the connector joint

 

Cleaning products

  • *General cleaning and removal of any accumulated sand or mud on a connector should be performed using spray based contact cleaner (isopropyl alcohol)
  • New grease must be applied again prior to mating
  • Always use Loctite 5910 to lock non-metallic (PEEK) connectors
  • For locking metallic connectors, the use of Loctite 243 is recommended
