Cellpack Heat Shrink Tubing 2:1 SR1F 38.1/19.1 mm Black 1 m 457285

Heat shrink tubing with a 2:1 shrink ratio, supplied diameter 38.1 mm and recovered diameter 19.1 mm, in black. Made from cross-linked polyolefin, it offers reliable insulation and protection for cables and components. The tubing shrinks when heated to a minimum of +90°C, conforming tightly to the underlying object.

Advantages

Provides electrical insulation and mechanical protection. The 2:1 ratio allows the tubing to fit snugly over irregular shapes. Self-extinguishing material reduces fire propagation risk. Resistant to ultraviolet light, making it suitable for outdoor use.

Suitable for

• Insulating electrical connections and splices
• Protecting cables from abrasion and moisture
• Bundling wires in automotive and industrial applications
• Repairing damaged cable jackets
