Heat Shrink Tubing 2:1 Ratio — Reliable Wire Insulation from Φ0.6mm to Φ210mm
Exposed wire splices, bare connector terminals, and unprotected solder joints are a constant headache for electricians, automotive technicians, hobbyists, and DIYers. One wrong contact and you're dealing with shorts, corrosion, or worse. This heat shrink tubing gives you a fast, clean, and durable solution — just slide it on, apply heat, and you're done.
Each piece is 1 meter (≈39.4") long and made from flame-retardant polyolefin with a 2:1 shrink ratio. Available in diameters from Φ0.6mm (≈0.024") up to Φ210mm (≈8.27"), and in 7 colors — White, Red, Green, Blue, Transparent, Yellow, and Black — so you can color-code wiring runs or match your project's aesthetic. The expanded diameter fits over the component; heat causes it to recover tightly around the substrate.
Typical applications include automotive wiring harness repair, marine cable protection, RC hobby wire management, home electrical DIY, and industrial cable bundling. The wide size range makes this a go-to heat shrink wire sleeving solution whether you're insulating a single 24 AWG wire or wrapping a large conduit bundle.
