SubConn handling instructions

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

Handling

• Connectors must be greased with MOLYKOTE® 44 Medium before every mating
• Always grease O-rings on BH, BCR and FCR connectors with Molykote 111
• Disconnect by pulling straight out, 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
• 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
• All current ratings are based on the connector being submerged in water
• The locking sleeve must be hand-tightened only

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 a minimum of 1/10 of the socket depth should be applied to the female connector
• The inner edge of all sockets should be completely covered, and a thin 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 all contacts and in the sockets
• To confirm that grease has been sufficiently applied, de-mate and check for grease on every male contact. 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 a 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 contaminations on a connector should be performed using spray-based contact cleaner (Isopropyl alcohol)
• New grease must be applied again prior to mating
  
  

Thread locking of connectors

• All threads shall be clean and free of any foreign particles
• Ensure the threaded hole is clean and free from foreign particles
• For locking metallic connectors, the use of LOCTITE® 243 is recommended
• Always use LOCTITE® 5970 to lock non-metallic (PEEK) connectors

Note: Acetone creates stress-induced cracking in PEEK material

Inline recommended bending radius

Recommended oil for pressure-balanced systems:

• MacArtney recommends DC-200/350 or PMX-200/350 in oil-compensated systems

Additional coax information

• Dry mating only
• Not suitable for open-face pressure or water-block applications
• Locking sleeves are required
• A dummy connector is required when coax connectors are unmated

Greasing of coax:

• Avoid greasing the actual coax, only grease the rubber parts
• After greasing, fully mate the male and female coax connector
• To confirm that grease has been sufficiently applied, de-mate and check for grease on every male contact, and confirm nothing has been applied to the coax. Then re-mate the connector
