In modern electrical systems, splice locations often represent one of the most vulnerable points in the wire harness. Hidden within constrained spaces and exposed to moisture, fluids, temperature cycling, and vibration, unprotected splices can become a source of corrosion, electrical degradation, and system-level failures. TE Connectivity's Performance Materials splice sealing portfolio helps engineers address these challenges through proven materials science and application expertise.

Our splice sealing portfolio combines insulation, environmental sealing, strain relief, and mechanical reinforcement within a single integrated solution. Whether you're designing automotive harnesses, EV battery systems, industrial equipment, or transportation platforms, TE offers solutions engineered for long-term durability and manufacturing efficiency.
