Attention 

 
For hybrid connectors (eg fibre optic and coax combined) it is necessary to ensure that only 
the region of the insulating elastomer must be greased. Fibre-optic and coaxial contacts 
must be kept absolutely free from grease to prevent losses.

Right:

Picture: grease filling of plug 

 

Lightly  grease  the  locking  threads  of  the  receptacles,  pressure  hull  penetrators  and  the 
through  bulkhead  receptacles  e.c.  with  GISMA-FETT  LP  430  (strongly  recommended  at 
stainless steel and titanium threads). 

Dirty connectors to be purged with GISMA foam cleaner (SCHAUMREINIGER). Allow three 
minutes to react. In case of strong dirt repeat the procedure. Then rinse with clean water. 
Following rinse with the enclosed cleaning liquid (SPÜLLÖSUNG) to neutralize foam cleaner. 

Check to see if the plugs locking sleeve runs smoothly.
