HellermannTyton HA67 6:1 Adhesive-Lined Heat Shrink Tubing 19mm/3.2mm Black 1m

With a 6:1 shrink ratio and adhesive lining, this heat shrink tubing provides reliable sealing and insulation for demanding cable applications. Supplied diameter 19 mm recovers to 3.2 mm, creating a durable, water-resistant barrier.

Overview

The HellermannTyton HA67 series heat shrink tubing is made from cross-linked polyolefin with an inner adhesive layer. When heated, the tubing shrinks to 1/6 of its original diameter, while the adhesive melts to form a moisture-resistant seal. This 1-meter length in black is suitable for electrical insulation, strain relief, and environmental protection of cables and connectors.
