16mm Heat Shrink Tubing 2:1 — Reliable Insulation for Wire, Cable & Connector Protection
Whether you're repairing a frayed automotive harness, organizing a home theater cable run, or protecting marine wiring from moisture, finding heat shrink tubing that actually fits large-diameter cables without splitting or sliding off is a real frustration. DIYers, electricians, and hobbyists alike need a tubing that goes on easily, shrinks cleanly, and stays put — in the right color for quick identification.
This listing offers 16mm (5/8") diameter, 2:1 shrink ratio polyolefin heat shrink tubing, available in seven colors — Black, White, Red, Green, Yellow, Blue, and Transparent (Clear) — and in four cut lengths: 1 Meter (≈3.3 ft), 5 Meter (≈16.4 ft), 20 Meter (≈65.6 ft), and 100 Meter (≈328 ft). The tubing shrinks down to approximately 8mm (5/16") when heat is applied, accommodating a wide range of cable and bundle diameters in between.
Typical use cases include automotive wiring harness repair and color-coding, electrical panel cable management, marine and RV wiring protection, and workshop tool cord insulation. The color variety makes this a go-to choice for anyone needing color-coded heat shrink wire sleeving for multi-circuit identification or neat cable bundling on larger gauge wires.
