HellermannTyton HIS-PACK-19,1/9,5-RD Tubo termorretráctil, 2:1, rojo, 19,1 mm expandido, 9,5 mm recuperado, longitud 5 m, caja dispensadora

Electrical insulation and cable bundling demand reliable protection against abrasion, moisture, and strain. This red heat shrink tubing from HellermannTyton provides a 2:1 shrink ratio, recovering from an expanded diameter of 19.1 mm to 9.5 mm, ensuring a tight, secure fit over connectors, splices, and wire harnesses. Supplied in a convenient dispenser box with a 5 m length, it offers an efficient solution for workshop and field use.

Who is it for

Electricians, panel builders, and maintenance technicians who need durable, easy-to-apply insulation for electrical connections, cable bundling, and strain relief. The dispenser box keeps the tubing clean and tangle-free, ideal for frequent use.

Tips

For best results, use a heat gun set to at least 90°C and apply heat evenly around the tubing until it conforms tightly to the substrate. Avoid overheating to prevent discolouration or damage. Store in a cool, dry place away from direct sunlight to maintain material properties.
