Gamvdout heat shrink tubing is manufactured to be safe for users and the environment: it does not emit toxic gases and has a significantly shortened degradation time. The material also delivers strong fireproof, waterproof and voltage-resistant performance, making it dependable for electrical work. With a 2:1 shrink ratio, these tubes conform tightly to wires of different shapes, offering effective electrical isolation and insulation for exposed conductors or wire connections and helping to extend the service life of cables. Installation is simple—slide the tube over the wire or splice, apply heat with a heat gun or a lighter, and it will shrink within seconds; no special tools or professional skills are required, so it’s suitable for both technicians and DIYers. Use this tubing for electrical insulation, bundling and organization, color coding, mechanical protection, cable splicing and routine maintenance. It’s an excellent choice for automotive, home furnishings, audio/video, marine and other applications. The kit includes ten sizes to cover a wide range of needs: 30/35/40/45/50/60/70/80/90/100mm. Each size comes on a 5M length that can be freely cut to the exact length you need.
