Wirefy 1" Heat Shrink Tubing (3:1) — Adhesive-Lined Black, 50ft Roll, 1 Rail, 1 Count, 1 Pack

Durable, adhesive-lined 1-inch heat shrink tubing on a 50-foot roll. This Wirefy tubing has a 3:1 shrink ratio, recovering to one-third of its original diameter for a snug, secure fit. The inner adhesive layer melts and bonds when heated, creating a rigid, waterproof seal that protects connections from moisture, fluids, and chemicals. Ideal for electrical insulation, environmental sealing, strain relief, wire grouping and identification, thermal insulation, and surface protection against abrasion, peeling, and denting. UL listed and compliant with applicable electrical safety standards, supplied as a single 1 Rail/1 Count pack to cover multiple projects.
