    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.
    ASTM D495—Rated to protect against electrical arcs, which cause surface damage that can lead to short circuits or fires.
