Red PVC Heat Shrink Tubing — Reliable Wire & Battery Insulation from 7mm to 280mm
Whether you're rebuilding a battery pack, organizing a wiring harness, or protecting exposed terminals in your workshop, finding heat shrink tubing that actually fits your components — without guessing — is a constant frustration. This red PVC heat shrink tubing is stocked in an unusually wide range of flat widths, from 7mm (≈0.28") all the way up to 280mm (≈11"), so you can cover everything from thin signal wires to large-diameter battery cells in a single order.
Each roll is made from flexible PVC with a standard 2:1 shrink ratio. Flat widths available: 7mm (≈0.28"), 9mm (≈0.35"), 12mm (≈0.47"), 17mm (≈0.67"), 23mm (≈0.91"), 27mm (≈1.06"), 29.5mm (≈1.16"), 31mm (≈1.22"), 36mm (≈1.42"), 40mm (≈1.57"), 43mm (≈1.69"), 45mm (≈1.77"), 50mm (≈1.97"), 55mm (≈2.17"), 60mm (≈2.36"), 66mm (≈2.60"), 70mm (≈2.76"), 75mm (≈2.95"), 80mm (≈3.15"), 83mm (≈3.27"), 85mm (≈3.35"), 91mm (≈3.58"), 95mm (≈3.74"), 103mm (≈4.06"), 110mm (≈4.33"), 115mm (≈4.53"), 125mm (≈4.92"), 130mm (≈5.12"), 135mm (≈5.31"), 140mm (≈5.51"), 150mm (≈5.91"), 160mm (≈6.30"), 170mm (≈6.69"), 180mm (≈7.09"), 280mm (≈11.02"). Length options: 1 Meter (≈3.3 ft), 2 Meter (≈6.6 ft), 5 Meter (≈16.4 ft), 10 Meter (≈32.8 ft), and 20 Meter (≈65.6 ft).
Typical use cases include DIY lithium battery pack assembly and cell-level insulation, automotive wire loom protection and color-coding, and electronics repair where red heat shrink tubing for wire identification is needed in a workshop or field setting.
