ES Caps
Semirigid, adhesive-lined, polyolefin
heat-shrinkable sealing caps
Adhesive-lined, heat-shrinkable
ES Caps are specifically designed
to provide mechanical and
environmental protection of stub
splices in electrical harnesses.
Clear ES Caps allow see-through
inspection; black ES Caps
are flame-retardant. The radiation-
crosslinked polyolefin outer jacket is
mechanically tough, providing
abrasion protection. The cap’s inner
layer is a unique hot-melt adhesive,
specially formulated to seal to most
types of commercial wire insulation
and to perform well at an
extended temperature range.
The thick adhesive forms an
effective barrier against fluids
and moisture, helping protect
the harness from the effects of
corrosion and water wicking.
