Overview

Meet the ROCKDIG braided sleeving: a 20 ft length of heat shrinkable protection designed to tidy and shield cables and wiring harnesses. Made from PET fiber and PE filaments, this sleeving can shrink its inner diameter to half its original size, allowing a snug wrap around bundles, twists, and connectors. The result is a cleaner, organized setup with an integrated layer of insulation and protection.

Key benefits at a glance

  • 2:1 shrink ratio enables a tight fit over irregular shapes and components
  • Notable noise reduction, enhanced flexibility, and solid heat resistance
  • Good insulation with protection from moisture and abrasion for cables and wires
  • Easy to use: shrink quickly and evenly with a heat gun for a secure finish
  • Snug fit over wires and connectors to keep bundles neat and organized

Practical uses and versatility

  • Bundling and protecting cables in electrical projects, from hobby builds to professional work
  • Electrical insulation, strain relief, and corrosion protection for wiring harnesses
  • Solder insulation and wire bundling in control panels, automotive projects, or consumer electronics
  • Install within irregular tubes thanks to the 2:1 shrink characteristics, enabling adaptable coverage

Temperature performance: operating from -55°C to +135°C (-67°F to 275°F); the maximum continuous use temperature is 135°C (275°F). This range supports use across indoor and moderately demanding environments where heat and moisture are factors.

Why choose ROCKDIG sleeving?

Beyond the numbers, the braided construction balances stiffness with flexibility, letting you wrap around tight corners and connectors without adding excessive bulk. The PET/PE blend offers durable insulation and abrasion resistance while keeping the overall profile lightweight.

Tips for best results

  • Prepare the cable bundle, slide the sleeving in place, and apply heat evenly with a heat gun for uniform shrinking.
  • For irregular tubes, let the sleeving shrink to the contour to achieve a neat finish.
  • After shrinking, verify fit and trim excess length if needed for a clean look and protection.
