HellermannTyton 300-30320 kutistesukka - polyolefiini - musta - 3,0 mm sisähalkaisija - 100 m rulla

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
• Color-coding and identification of cables
• Bundling and organizing wires in control panels and harnesses
