Molded Parts

Applications
TE heat-shrinkable molded
parts in -25 material aredesigned to be used inconjunction with other
System 25 components
such as DR-25 tubing and
S1125 adhesive, providing
a complete cable harness
system capability.
-25 parts have been
specifically formulated
and designed to provide
optimum high-temperature
fluid resistance and longterm heat resistance.
This unique balance ofproperties makes -25 parts
particularly suitable forsealing and strain relief
at connector-cableterminations and cable-tocable transitions on military
vehicle cables andharnesses. Available in awide range of configurations, -25 parts will operatefrom -75°C to 150°C [-103°F
to 302°F] for long periods.
The standard color is black.
