9.6 DIELECTRIC GREASE APPLICATION
Dielectric grease helps to prevent corrosion of electrical
contacts and improper conductivity between contacts from
moisture intrusion. Open and sealed connectors benefit
from the application of dielectric grease.
9.6.1 Installation
1. Apply dielectric grease to plug/male connector housing
which typically contains sockets contact/female
terminals.
Note: Use dielectric grease in a tube for larger connection
points or apply with a syringe for small connectors.
2. Leave a thin layer of dielectric grease on the face of the
connector.
3. Assemble the connector system immediately to prevent
moisture ingress or dust contamination.
4. Pierce one of the unused wire seals prior to assembly if
the connector system tends to trap air (i.e. AMP Seal)
and then install a seal plug.
The following connector systems are specifically addressed
because of their widespread use. However, this guidance
may be applied to similar devices:
1. Deutsch HD, DT, DTM, DRC Series
The Deutsch connector system is widely used for harsh
environment interconnect. Follow the general guidance for
installation.
2. AMP Seal
The AMP Seal connector system is used on the Control ADE
Platform and Ground Modules.
Apply dielectric grease to the plug/male connector housing
which typically contains socket contacts/female terminals. If
trapped air prevents the connector from latching, pierce one
of the unused wire seals. After assembly, install a seal plug in
that location to prevent moisture ingress.
Note: Seal plugs may be installed by the wire harness
manufacturer if an unused wire seal becomes compromised
(wire inserted in the wrong cavity during assembly and the
corrected).
