For extremely low temperature deployments, (below -40ºC) use Molykote 33 or Uniflor
8911 grease
To apply the grease:
1. Apply a layer of grease to the seismometer end of the cable connector as follows:
1. If the connector is dry, apply a layer of grease approximately 2 mm thick.
2. If the connector is already wet (for example, in the field), apply a layer of grease
approximately 8 mm thick.
2. To distribute the grease into the socket holes and onto the connector prongs, push
together the two ends of the connector, then pull them apart again to verify that the
grease has been distributed sufficiently.
3. Once the grease distribution has been verified, reconnect the ends and tighten the red
locking sleeves to prevent the connectors from coming apart.
