Questions about this product
- What wire sizes does this heat shrink kit cover?
- The 2:1 tubing runs from 1.0 mm up to 13.0 mm before shrinking. The 3:1 sizes go from 1.5 mm up to 25.0 mm. Between both ratios you can cover thin signal wires through to larger battery and cable bundles.
- What temperature do I need to shrink this tubing?
- It starts shrinking at about 70°C and fully shrinks by 125°C. A heat gun is the easiest tool, but a lighter or hot air also works if you keep the flame moving. Each piece is about 45 mm long, so cut to length first.
- Is this tubing safe for higher voltage connections?
- Yes. It's rated to 600V with a dielectric strength of 15 kV/mm, so it insulates typical low and line voltage wiring. The polyolefin material is VW-1 flame rated and works from -55°C to 125°C. Always insulate a properly made joint, not a bare splice.
