High shrink ratio: This heat shrink tubing shrinks down to a fraction of its original diameter, creating a tight seal around irregular connectors and wire splices Flame retardant: This heat shrink sleeving self-extinguishes when the heat source is removed, adding a safety layer to electrical repairs and cable bundling Insulation protection: This shrink tubing wraps wires in a protective layer that prevents shorts, keeping conductive materials safely separated in tight spaces Even shrinkage: This cable wrap contracts uniformly along its entire length, avoiding thin spots or bubbles that could compromise the protective barrier Moisture seal: This cable sleeve forms a water-resistant barrier around exposed wires, protecting connections from damp environments and weather exposure, Manufacturer: WWYYZAYC
