Heat-shrink for vehicle and trailer wiring: thin-wall 2:1 tubing, adhesive-lined 3:1 tubing for waterproof joints, adhesive end caps and solder sleeves. Prices are business prices excl. VAT; sold per dispenser box, roll or pack. Articles without a price are supplied on request.
Selection guide
Ø before shrinking larger than the thickest part (connector, splice); Ø after shrinking smaller than the thinnest part (cable).
3:1 when the diameters differ a lot, for example a connector body on a thin cable. 2:1 for wires, terminals and bundles of even diameter.
With adhesive for waterproof sealing and strain relief: trailer lighting, under-body wiring, agricultural machinery. Without adhesive for insulating, marking and bundling.
Choose by conductor cross-section in mm² — the range is printed on every article.
Join, insulate and seal in one step. Choose by the outer diameter of the joined wires.
Allow for length shrinkage of typically 5–10 % when cutting.
| Ø before → after | Ratio | Suits cable / bundle Ø |
|---|---|---|
| 3 → 1 mm | 3:1 | 1–2.4 mm |
| 3.2 → 1.6 mm | 2:1 | 1.6–2.6 mm |
| 4.8 → 2.4 mm | 2:1 | 2.4–3.8 mm |
| 6 → 2 mm | 3:1 | 2–4.8 mm |
| 6.4 → 3.2 mm | 2:1 | 3.2–5.1 mm |
| 9 → 3 mm | 3:1 | 3–7.2 mm |
| 9.5 → 4.8 mm | 2:1 | 4.8–7.6 mm |
| 12 → 4 mm | 3:1 | 4–9.6 mm |
| 12.7 → 6.4 mm | 2:1 | 6.4–10.2 mm |
| 18 → 6 mm | 3:1 | 6–14.4 mm |
| 19 → 9.5 mm | 2:1 | 9.5–15.2 mm |
| 24 → 8 mm | 3:1 | 8–19.2 mm |
| 25.4 → 12.7 mm | 2:1 | 12.7–20.3 mm |
Applications
The Ø before shrinking must fit over the thickest part, the Ø after shrinking must be smaller than the cable. Each article shows a guide value for the cable or bundle diameter.
With adhesive when the joint must be waterproof or needs strain relief (outdoor, under-body, trailer lighting). Without adhesive for insulation, marking and bundling.
Per dispenser box, roll or pack, excl. VAT. The price per metre or per piece is shown for comparison. You always order whole sales units.
Polyolefin heat-shrink typically shrinks from about 90–120 °C; adhesive-lined tubing needs enough heat for the adhesive to flow. Use a hot-air gun; an open flame only with care, as it can scorch the tubing.
