Hermetic Connectors
Glass Sealed Hermetic Connectors
Users around the world have found that ITT Cannon
hermetic connectors function reliably under extreme
environmental conditions. Hermetic connectors are
impervious to most liquids and gases, including acids,
alkalis, oils, gasoline, jet fuel and hydraulic fluids. They
can take shock loads as high as 100 g’s with no loss in
hermeticity, and can take extremes of both heat and
cold with no loss of performance.
Manufacturing Expertise
Cannon compression glass seals are strong. A 50,000
psi compression stress generates a sealing force that
can withstand up to 10,000 psi differential pressure
(pressure varies with connector type). Since it is
independent of adhesion, the seal has a temperature
capability of -260° to +450° Fahrenheit. The seal has
high radiation resistance and a leak rate of less than
10
-8
cc per second.
All ITT Cannon hermetic connectors are 100% tested
after fabrication. A stringent examination ensures that
all military specifications are met. The product is tested
for leak performance, dielectric withstanding voltage
and insulation resistance.

Compression Glass Seals
Glass is an ideal electrical insulating material for
connectors. Its mechanical strength readily supports
contacts. The compression seal is achieved by placing
a glass preform within the surrounding metal shell,
heating the glass and shell to the glass melting
temperature, and then cooling the assembly. As the
assembly cools, the glass becomes rigid and the metal
shell begins to compress the glass. This compression
provides a very high strength, high reliability hermetic
seal.
Custom Design Capabilities
Custom hermetic connectors can be manufactured to
meet special requirements. Hermetic connectors have
been developed to withstand exposure to propellants,
high pressure and high temperature conditions for
missiles, “sub-safe” connectors for penetration feed-
thru on ships and submarines, connectors for aircraft
engines and many more.
This catalog provides a sample of the standard
hermetic connectors available from Cannon. If you
don’t immediately find the connector that is right for
your application, we encourage you to call an ITT
Cannon technical sales representative in your area or
complete and mail the business reply card at the back
of this catalog.
