Heat-Shrink Tubing
How to choose heat-shrink tubing
Wall thickness
thin wall suits 2.4mm electronics, normal wall fits 25.4mm cable.
Colour
pick black/red/yellow for phase marks, or blue for neutral, from the live grid above.
Material
silicone/rubber copes with heat, while standard plastic serves dry indoor joints.
Length
1.2m covers a few fixes, 100m suits daily installation across the range.
Form
EMI sleeves wrap a built loom, whereas heat shrink needs the wire ends free. Conduit and housings are rigid alternatives, not for shrinking down.
What's good
- Thin wall heat shrink fits tight enclosures where a 2.4mm cable leaves no slack.
- Normal wall tubing adds a thicker plastic layer, suiting 25.4mm mains feeds needing cover.
- Non-slip tubing gives grip on tool handles, a different job from slick insulation.
- EMI sleeves shield looms from signal noise, useful where basic tube fails.
Things to watch
- Thin wall types lack the mechanical strength for exposed outdoor conduit runs.
- Non-slip rolls often appear in single colours like blue, limiting black/red/yellow coding.
- EMI sleeves are bulkier than 2:1 normal wall, awkward in a small junction box.
- A 100m reel eats shelf space if your repair only needs 1.2m.
Care & maintenance
Sunlight
Keep plastic and silicone/rubber tube out of direct sun to stop the colour fading.
Moisture
Wipe metal conduit and housings dry, as trapped moisture marks stainless steel.
Storage
Bag the offcuts of thin wall material so dust does not stick to the soft wall.
