- Connector Protection — strain relief on USB, DC barrel, and audio connectors
- Cable Bundling — group multiple wires into a neat harness
- PCB Component Protection — insulate exposed leads on through-hole components
- Automotive Repair — waterproof wire splice insulation (use adhesive-lined variant for full waterproofing)
FAQ
Q: Can I use a lighter instead of a heat gun?
A: Yes, for small sizes (1–3mm). Keep the flame moving to avoid burning. A heat gun provides more even and controlled shrinkage, especially for larger sizes (5–8mm).
Q: Is this tubing waterproof?
A: Standard 2:1 polyolefin tubing is water-resistant but not fully waterproof. For waterproof applications, use adhesive-lined (3:1) heat shrink which has a hot-melt adhesive inner layer.
Q: What size should I use for JST PH2.0 wires?
A: JST PH2.0 uses 26–28AWG wire (~0.4mm conductor). Use 1.5mm or 2mm heat shrink for individual wire insulation, or 3mm–4mm for covering the connector crimp area.
