HellermannTyton 416-12046 Manga Termorretrátil 3:1, 8 mm, Preto, Rolo de 1000 m

Protecting cables and wire bundles from abrasion, moisture, and environmental stress is a constant challenge in electrical installations. The HellermannTyton 416-12046 heat shrink tubing provides a reliable, tight-fitting insulation sleeve that shrinks to 1/3 of its original diameter when heated, creating a durable and professional finish.

Who is it for

This tubing is ideal for electricians, panel builders, and maintenance technicians who need to insulate, bundle, or repair cables in industrial, automotive, or marine environments. It is especially suited for applications requiring a high shrink ratio to cover connectors or irregular shapes.
