6.3 APPLYING SILICONE DIELECTRIC COMPOUND TO
AMP CONNECTORS
Silicone Dielectric Compound must be used on the AMP con-
nections for the following reasons:
• To prevent oxidation at the mechanical joint between male
and female pins.
• To prevent electrical malfunction caused by low level con-
ductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric Com-
pound to the electrical connectors.
1. To prevent oxidation and low level conductivity, silicone
dielectric grease must be packed completely around
male and female pins on the inside of the connector
after the mating of the housing to the header. This is
easily achieved by using a syringe to fill the header with
silicone dielectric compound, to a point just above the
top of the male pins inside the header. When assem-
bling the housing to the header, it is possible that the
housing will become air locked, thus preventing the
housing latch from engaging.
2. Pierce one of the unused wire seals to allow the trapped
air inside the housing to escape.
3. Install a hole plug into this and/or any unused wire seal
that has silicone dielectric compound escaping from it.
