HellermannTyton HIS-3 kutistesukka 3,2 mm musta 1,2 m polyolefiini 2:1

The HellermannTyton 300-30950 is a high-quality heat shrink tubing from the HIS-3 series, designed for reliable insulation, protection, and strain relief of electrical connections and cables. Made from flexible polyolefin (PO-X) with a 2:1 shrink ratio, this black tubing shrinks to half its supplied diameter when heated, providing a tight, secure fit. With a supplied inner diameter of 3.2 mm and a recovered inner diameter of 1.6 mm, it is ideal for a wide range of applications in automotive, industrial, and electronic environments. Each piece is 1.2 meters long, offering ample length for multiple uses.

Advantages

This heat shrink tubing offers excellent electrical insulation with a dielectric strength greater than 20 kV/mm, ensuring safe operation in demanding conditions. It is flame retardant (UL224 VW-1) and self-extinguishing, enhancing safety. The tubing provides good UV and chemical resistance, making it suitable for outdoor and harsh environments. Its wide operating temperature range from -55 °C to +125 °C ensures reliable performance in extreme temperatures. The 2:1 shrink ratio allows for easy installation over connectors and irregular shapes.

Suitable for

• Insulating electrical connections and splices
• Protecting cables and wires from abrasion, moisture, and chemicals
