4:1 Adhesive Heat Shrink Tubing

Dual Wall Design | 1 Metre Length | Black Cable Protection

Black 4:1 Dual Wall Adhesive Heat Shrink Tubing

Product Overview

Protect and insulate wires, cable joints and electrical connections with this 4:1 dual-wall heat shrink tubing. Designed to shrink tightly when heated, it helps create a secure covering around compatible cables and connectors.

The inner heat-activated adhesive layer melts during proper application to help seal gaps and provide additional protection against moisture and environmental exposure. Supplied in a convenient 1-metre length, this black tubing is suitable for electrical repairs, automotive wiring and general cable management projects.
