DIELECTRIC GREASE
The following figures show the proper application of
dielectric grease on J-tech type of connectors.
Dielectric grease is need when assembling J-tech type
connectors. A bead of grease needs to be applied on the O-
ring and face of a socket (female) connector and on only the
O-ring of a pin (male) connector.
The size of the grease bead on the O-ring is as follows:
• On a 3-pin connector a 1,59 mm (1/16 in) bead is
required.
• On a 24-pin connector a 3,18 mm (1/8 in) bead is
required.
• On a 37-pin connector a 4,76 mm (3/16 in) bead is
required.
Place a small amount of grease on your finger for the
application on the connector’s face. Wipe your finger across
the face, leaving grease inside the socket holes and less
than 0,025 mm (0.001 in) on the connector’s face. This helps
ensure that water will be kept out of the connectors and
keeps the pins from fretting.
