7.9mm Heat Shrink Tubing 3:1 — Reliable Waterproof Insulation for Every Wiring Job

Exposed solder joints, frayed wire ends, and unprotected connectors are the silent culprits behind electrical failures — whether you are wiring a trailer, repairing an automotive harness, or tidying up a home workshop project. This 7.9mm heat shrink tubing with a 3:1 shrink ratio gives DIYers, electricians, and hobbyists a fast, clean way to insulate and protect connections without tape, messy compounds, or bulky connectors.

Each order covers a single continuous length of tubing — available in 1m (approx. 3.3ft), 2m (approx. 6.6ft), 5m (approx. 16.4ft), or 10m (approx. 32.8ft) — in your choice of 8 colors: Black, White, Red, Green, Yellow, Blue, Transparent, or a color-coded mix. The inner diameter before shrinking is 7.9mm; after full heat recovery at a 3:1 ratio, the recovered diameter is typically around 2.6mm (approx. 0.10 inch). Wall thickness and exact recovered dimensions may vary slightly by color batch — see variant options for confirmation.

Typical applications include automotive wiring harness repair, marine and trailer connector sealing, RC vehicle wiring, solar panel cable management, and workshop wire organization. The color variety makes it especially useful for circuit identification in multi-conductor installations and DIY electrical panel work.

🔌 Compatibility: Fits wire bundles and connectors up to approximately 7.5mm in
