Product details

Overview

Discover ROCKDIG's 20 ft heat shrink braided sleeving, a compact shielding option designed to protect cables, wires, and wiring harnesses. Crafted from PET fiber and PE filaments, it compresses down to half of its original inner diameter, enabling neat bundling and a secure fit around diverse cables and connectors.

With a broad temperature window from -55°C to 135°C and a continuous-use ceiling at 135°C, the sleeving is built for resilience across indoor and outdoor setups. The braided construction helps dampen noise, preserve flexibility, and resist heat while delivering reliable insulation and protection from moisture and abrasion in everyday installations.

Key benefits

  • Shrinks quickly and evenly to a snug 2:1 profile with a heat gun, simplifying complex cable runs.
  • Flexible enough to follow irregular paths without losing protective coverage.
  • Provides insulation alongside moisture and abrasion protection for cables and connectors.
  • Ideal for bundling, strain relief, corrosion protection, solder insulation, and general wire management.

Ideal uses

  • Electrical projects that require tidy cable organization and enhanced shielding.
  • Automotive, industrial, or DIY builds where insulation and protection are priorities.
  • Situations with irregular tubes or hard-to-fit routes where a standard sleeve falls short.

Installation tips and specs

Easy to use — slide the sleeve over wires or connectors and apply heat until it contracts to half its diameter. Each package includes a 12 mm (1/2") diameter sleeve, 20 ft in length, with a 2:1 shrink ratio for versatile applications.

Why ROCKDIG
