Product details

Overview

The ROCKDIG 20 ft heat shrinkable braided sleeving is crafted from PET fiber and PE filaments, delivering a durable, flexible sleeve designed to protect and organize cables and wiring harnesses. Its impressive 2:1 shrink ratio lets the inner diameter contract to half of the original size, enabling a snug, secure fit over wires, connectors, and even irregular tubes.

Constructed to handle demanding environments, this sleeving covers a broad temperature window—from -55°C to 135°C (-67°F to 275°F)—with a maximum continuous use temperature of 135°C (275°F). This combination of material science and design helps maintain insulation and protection in fluctuating conditions.

What makes it stand out

  • Material strength: PET fiber and PE filaments provide resilience, insulation, and a barrier against moisture and abrasion.
  • Efficient shrinkage: A 2:1 ratio enables quick, even reduction in diameter for a snug wrap around cables and connectors.
  • Thermal tolerance: Operates reliably from -55°C up to 135°C with a solid continuous-use ceiling.
  • Noise and protection: Notable noise reduction, flexible bending, and robust heat resistance contribute to cleaner, safer cable management.
  • Ease of use: Shrinks quickly with a heat gun and fits tightly around wires for a neat, professional finish.

Usage tips

  • Prep: Measure, cut to length, and slip over cables or locations needing added insulation and protection.
  • Install: Apply heat evenly with a heat gun until it contracts to the desired diameter, ensuring a uniform wrap.
  • Care: Avoid overheating to protect sleeve integrity and consistency of the shrinkage.

Applications

  • Bundle and protect cables in electrical projects and wiring harnesses.
  • Electrical insulation, strain relief, and corrosion protection for exposed wiring.
  • Solder insulation, wire bundling, and general cable management in tight or irregular spaces.
