    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.

  • Page 37 This could lead to damage to the seals and insulation within the socket contacts. Plugs do not require full pressure watertight protective cap for protection. GISMA advise the fitting of POM caps to protect plugs against marine growth. It is good practice to always fit the protective cap when a connector is unmated topside prior to deployment to provide mechanical protection.
