Mating
The clamp ring should be rotated clockwise by hand until tight. The connectors are designed
to remain clamped together with only firm hand tightness on the clamp ring. If a clamping
torque is required this
made Tronic tool (T11367) may be used to apply this torque.
Post Mating Checks
Full engagement of the connectors can be checked through the viewing hole in the clamp
ring. If the connectors are fully mated then no gap should be visible between the plug and
receptacle.
Cathodic Protection
Stainless steel 316L (UNS S31603) diver mate connectors must be connected to the CP
(Cathodic Protection) system at all times. Super Duplex stainless steel (UNS S32550)
connectors should be isolated from the CP system to reduce the possibility of hydrogen
embrittlement.
