3:1 SHRINK RATIO & FAST CONTRACTION SPEED: Shrinks to 1/3 of its original diameter and seals extremely tightly, solving the issue of many 2:1 shrink tubes that don't shrink enough and therefore don't seal tightly enough.
Shrink temperature: 80 to 125°C. Provides a professional connection within seconds.
INCLUDES ADHESIVE COATING: When the heat shrink tubing is heated, it automatically releases adhesive and seals the connection extremely reliably.
DUAL WALL TUBING: The outer wall of the shrink tube provides extremely high abrasion resistance. The inner wall creates a consistently waterproof seal and excellent strain relief. Our solder connectors will also impress you! 7
