Insulator greasing
Before the initial coupling the front side of the socket connectors must be greased with
GISMA-grease EK2 (part no.: GISMA-FETT EK2), to fill the conical seal cavities with grease
(see drawing below). Greasing ensures that the two elastomer Insulators in the conical seals
can slide perfectly into its final position and thus best seal. After 20 underwater matings the
connector should be greased again.
For greasing the GISMA connectors - Grease EK2 is specified. The corresponding
compatibility of this Grease is with all elastomers used in GISMA (insulating, sealing
elements) given. At the same time, this product has excellent properties.
The grease EK2 is not conductive. By mating the GISMA connector the contact forces
applied mean the grease is completely displaced from the contact area, so that the grease
does not affect the contact resistance. At the same time this ensures a high Insulation
resistance - even with insertions in moist environments.
Typical properties
reduced friction and wear
prevents leakage
contact oxidation resistance
neutral against plastics
Amount of grease to be used
The Insulator should be greased so that the insulating sealing cone is 70-100 % filled with
grease.
