HellermannTyton 300-30320 Heat Shrink Tubing - Polyolefin - Black - 3.0mm ID - 100m Roll

The HellermannTyton 300-30320 is a high-quality heat shrink tubing made from cross-linked polyolefin, designed for reliable insulation, protection, and strain relief of electrical connections and cables. With a 2:1 shrink ratio and a supplied inner diameter of 3.0 mm, it shrinks to 1.5 mm upon heating, providing a tight, secure fit. This black tubing is supplied in a 100-meter roll, making it ideal for bulk applications in electrical, automotive, and industrial environments.

Advantages

Excellent electrical insulation with dielectric strength of 20 kV/mm. Flexible and durable with good UV and chemical resistance. Flame retardant (UL94 V2) and compliant with UL 224 and CSA standards. Easy to install with a minimum shrink temperature of +90°C.

Suitable for

• Insulating and protecting wire splices and terminals
• Strain relief for connectors and cable assemblies
