HellermannTyton HIS-1 Heat Shrink Tubing 12.7mm/6.4mm 2:1 5m Black Dispenser Box (300-31270)

The HellermannTyton HIS-1 heat shrink tubing is a high-quality, cross-linked polyolefin tubing designed for insulation, protection, and strain relief of electrical connections and cables. With a 2:1 shrink ratio, it shrinks to half its original diameter when heated, providing a tight, secure fit. This 5-meter length in a convenient dispenser box is ideal for professional and DIY applications.

Advantages

Excellent electrical insulation with dielectric strength of 15 kV/mm. Self-extinguishing (UL224 VW-1) for enhanced safety. Wide operating temperature range from -55°C to +125°C. Flexible and durable with high tensile strength and elongation. Easy to use with minimum shrink temperature of +90°C.

Suitable for

• Insulating and protecting wire splices and terminals
