Overview

Wirefy 5/16 inch heat shrink tubing delivers dependable protection for electrical wires and wiring bundles across a range of projects. Its 3:1 shrink ratio lets the tube compress to one third of its original diameter, yielding a compact, neat finish around conductors.

The adhesive-lined dual-wall construction melts and seals as it shrinks, creating a waterproof and oil-resistant bond designed to shield wires from moisture, dust, and contaminants in demanding environments.

Why choose this tubing

  • Three-to-one shrink ratio for a tight, professional wrap
  • Adhesive-lined dual wall to seal and insulate
  • Waterproof and oil-resistant when heated
  • 50 ft flexible roll for easy, custom-length cuts
  • Durable insulation that resists abrasion and heat
  • UL-listed for safety and consistent performance

Practical uses and scenarios

  • Automotive wiring harness protection under the hood and in engine bays
  • Marine electronics and outdoor installations exposed to moisture
  • Custom cable runs for lighting, sensors, and control wiring
  • Repairing insulation on damaged wires or harnesses without bulky kits
