HellermannTyton 380-03004 warmtekrimpkous-assortiment, 3:1, zwart, 130 delen

This heat shrink tubing assortment stands out by combining seven common diameters in a single black polyolefin kit, each piece cut to a uniform 100 mm length. The 3:1 shrink ratio grips irregular shapes more tightly than 2:1 tubing, making it a practical choice for repairs and harness work where a snug, durable seal is required.

Highlights

• 130 pieces across seven diameters: 1.5/0.5, 3.0/1.0, 4.5/1.5, 6.0/2.0, 9.0/3.0, 12.0/4.0, 18.0/6.0 mm (supplied/recovered)
• 3:1 shrink ratio for secure coverage on connectors and splices
• Cross-linked polyolefin material, black colour
• Operating temperature range -55 °C to +135 °C
• Self-extinguishing per UL94 V-2

In daily use

The assortment covers small signal wires up to larger cable bundles. Shrinkage starts at +90 °C and full recovery occurs at +110 °C, so a standard heat gun is sufficient. The tubing is not adhesive-lined; for moisture sealing, a separate adhesive or sealed connector is recommended.
