High-Temperature Self-Fusing Silicone Electrical Tape


Standard Profile	Tapered Profile

Create long-lasting seals around electrical connections, even in hot, cold, or wet conditions. Made of silicone, this tape stands up to chemicals, temperature changes, and UV rays, making it a good choice for insulating wiring and components in outdoor and other harsh environments. It is self-fusing, so it sticks to itself as you layer it for a secure seal that keeps moisture out. Also known as cold-shrink tape.

Tapered Profile—Thickest in the middle and thinner at the edges. This shape ensures that when you apply partially overlapping layers, the thickness remains uniform for a smooth, even surface and consistent dielectric strength. The center guide eliminates guesswork to help you precisely align each wrap.
