S4 6:1 High Shrink Ratio Heat Shrink Tube
Introduction
S4 6:1 Thick Wall Adhesive-Lined Heat Shrink Tubing is used to seal and protect cable splices, connectors, and irregular electrical assemblies exposed to moisture and harsh environments. The tubing shrinks tightly over large diameter variations and the internal adhesive forms a waterproof seal, making it ideal for underground feeder splice kits, 600V UF cable protection, and direct burial cable applications.
Features
Operating temperature: -55 to 105°C
Minimum fully recovery temperature: 125°C
Shrink ratio: 6:1
Halogen-free, RoHS compliant
Single or Dual wall optional
Standard Color: Black
