Tubo termorretrátil HellermannTyton HC12-52-PEUV-CL, 2:1, transparente, 12,7 mm de diâmetro interior fornecido, 1,2 m de comprimento, 50 unid.

Electricians and panel builders rely on this clear heat shrink tubing to insulate and protect cable splices, terminations, and wire bundles. The transparent polyolefin sleeve shrinks to half its original diameter when heated, creating a tight, durable seal that also allows visual inspection of the underlying connection.

Why choose it

Its transparent design makes it easy to identify wires and verify connections after shrinking, while the 2:1 shrink ratio ensures a snug fit over irregular shapes. The polyolefin material offers good chemical resistance and remains flexible across a wide temperature range, making it suitable for demanding electrical environments.

Ideal use cases

• Insulating and protecting electrical splices and terminations
• Bundling and organising wire harnesses
• Providing mechanical protection and strain relief for cables
• Colour-coding and identifying wires when used with labels underneath

Good to know

This tubing is supplied in 1.2 m lengths, which can be cut to the required size before shrinking. It is not flame retardant, so it should not be used in applications where fire resistance is critical.
