7.4 APPLYING SILICONE DIELECTRIC COMPOUND
TO AMP CONNECTORS
Silicone Dielectric Compound must be used on the AMP
connections for the following reasons:
• To prevent oxidation at the mechanical joint
between male and female pins.
• To prevent electrical malfunction caused by low level
conductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric
Compound to the electrical connectors.
1. To prevent oxidation and low level conductivity, sili-
cone 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 assembling 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.
