CellPack 203787 lämpökutistussukka, 3:1, ruskea, 3 mm, 15 m

For electricians and maintenance technicians, this brown heat shrink tubing provides reliable insulation and protection for wires and cables. With a 3:1 shrink ratio, it conforms tightly to irregular shapes, sealing out moisture and abrasion. The cross-linked polyolefin material is flame retardant and offers excellent chemical resistance, making it suitable for demanding environments. Supplied in a 15 m roll, it is ideal for color coding, bundling, and repairing cable harnesses in industrial and automotive applications.

Why choose it

This tubing offers a high shrink ratio for secure coverage over connectors and splices, combined with a wide operating temperature range. Its flame-retardant and chemical-resistant properties ensure long-term durability in harsh conditions.

Ideal use cases

• Electrical insulation of wire splices and terminations
• Cable bundling and strain relief
• Protection against abrasion and chemicals
• Color coding for circuit identification

Good to know

The tubing is not adhesive lined, so it is best suited for applications where a moisture-proof seal is not required. It can be cut to length as needed and shrinks uniformly with a heat gun.
